To prevent this issue from happening, be sure to use --complete-insert when running mysqldump. The addition of --create-options couldn't hurt.

Here's a quick example:

mysqldump --quote-names --complete-insert --create-options
--user=username --password=password database > dumpfile.sql

This is one of those errors that doesn't make any sense at all, until it sinks in. After awhile, it makes total sense.

1. Quit MAMP
2. Open the terminal and type: killall -9 mysqld
3. Restart MAMP

Try it for yourself. It'll blow your mind.

In this example, I'll show you how to add a links page to your site, without actually creating a page in the WordPress admin interface.

First, be sure you have a file called links.php in your theme's template directory.

<?php
/*
Template Name: Links
*/
?>

<?php get_header(); ?>

		<h2>My example links page</h2>
		<p>This is an example list of folks that I know.</p>

		<?php
		$bm = get_bookmarks( array(
		            'orderby'        => 'rand',
		            'order'          => 'ASC',
		            'limit'          => -1,
		            'hide_invisible' => 1,
		            'show_updated'   => 0,
		            'include'        => null,
		            'exclude'        => null,
		            'search'         => '.'));
		?>
		<?php foreach ($bm as $bookmark): ?>
		<p><?php echo $bookmark->link_name ?> - <?php echo $bookmark->link_url?></p>
	<?php endforeach; ?>

<?php get_footer(); ?>

Next, include this get_uri() function in your functions.php file:

function get_uri() {
	$request_uri = $_SERVER['REQUEST_URI'];
	// for consistency, check to see if trailing slash exists in URI request
	if (substr($request_uri, -1)!="/") {
		$request_uri = $request_uri."/";
	}
	preg_match_all('#[^/]+/#', $request_uri, $matches);
	// could've used explode() above, but this is more consistent across varied WP installs
	$uri = $matches[0];
	return $uri;
}

Add this set of functions and wordpress actions in your functions.php file:

	function links_template_title() {
		return "My Example Link Page";
	}

	function links_template() {
		$uri = get_uri();
		if ($uri[0]=='links/') {
			add_filter('wp_title', 'links_template_title', 20);
			// optional hook for the_title
			// add_filter('the_title', 'links_template_title', 20);
			include(TEMPLATEPATH . '/links.php');
			exit;
		}
	}

Now go to www.myexample.com/wordpress/links and enjoy your custom links page!

To take it a bit further, we could add another custom page with a few modifications, such as a local weather page. Just create another custom page template, page-weather.php and put it in your theme directory.

<?php
/*
Template Name: Weather Template
*/
?>

<?php get_header(); ?>

		<h2>My example weather page</h2>
		<p>This page could pull some information from the national weather service.</p>
		<p>Forecast: The rain in Spain falls mainly on the plain.</p>

<?php get_footer(); ?>

Add this to your functions.php file:

function weather_template_title() {
	return "Weather";
}

function weather_template() {
	$uri = get_uri();
	if ($uri[0]=='weather/') {
		add_filter('wp_title', 'weather_template_title', 20);
		// add_filter('the_title', 'weather_template_title', 20);
		include(TEMPLATEPATH . '/page-weather.php');
		exit;
	}
}

Now go to www.myexample.com/wordpress/weather and enjoy your custom weather page.

As of this writing, the plugin could only create custom roles on a blog level. There has been lots of discussion on the matter. The root of the problem is that each blog in a WPMU installation has its own capabilities stored separately.

I initially tried to create my own database table with custom roles and capabilities, but I soon realized that WordPress would require a great deal more customization to make this work. So, I decided to give in and store all the data the "native" way (which I consider somewhat dirty).

The following are modifications made to the includes/manager.php included with the capsman plugin. In short, I replaced all the CRUD functions with some quick loops that iterate through each blog in the network, making use of WPMU's get_blog_list() function.

Caveats:

1. This has only been tested on a simple level using WPMU 2.9.2.
2. Due to the nature of WPMU, it creates a lot of duplicate data in your database.
3. Performance could be better, but it crunched through 1200 blogs in about 10 seconds.

Let's take a look at includes/manager.php.

On Line 292, replace saveRoleCapabilities with the following foreach loop. I commented out the original code that was there, leaving it for reference.

// *********** begin paul wenzel's modifications...
// updates/saves capabilties for this role, for all blogs
$blog_list = get_blog_list( 0, 'all' );
foreach ($blog_list AS $blog) {
	switch_to_blog($blog['blog_id']);
	$this->saveRoleCapabilities($post['current'], $post['caps'], $post['level']);
}
// $this->saveRoleCapabilities($post['current'], $post['caps'], $post['level']); // Original Code
// ********* end paul wenzel's modifications

Around line 311, modify the call to createRole.

// *********** begin paul wenzel's modifications... create roles for all blogs
// TODO: Add WPMU/multisite check using function_exists(get_bloglist()).
$blog_list = get_blog_list( 0, 'all' );
foreach ($blog_list AS $blog) {
	switch_to_blog($blog['blog_id']);
	$newrole = $this->createRole($post['create-name']);
}

// **** Original Code
// if ( $newrole = $this->createRole($post['create-name']) ) {
// 	ak_admin_notify(__('New role created.', $this->ID));
// 	$this->current = $newrole;
// } else {
// 	ak_admin_error(__('Error: Failed creating the new role.', $this->ID));
// }

// ********* end paul wenzel's modifications

On Line 335, modify the createRole call, copying the current role to a new one.

// *********** begin paul wenzel's modifications... updates roles for all blogs
$blog_list = get_blog_list( 0, 'all' );
foreach ($blog_list AS $blog) {
	switch_to_blog($blog['blog_id']);
	$newrole = $this->createRole($post['copy-name'], $current->capabilities);
}

// *** Original Plugin Code
// if ( $newrole = $this->createRole($post['copy-name'], $current->capabilities) ) {
// 	ak_admin_notify(__('New role created.', $this->ID));
// 	$this->current = $newrole;
// } else {
// 	ak_admin_error(__('Error: Failed creating the new role.', $this->ID));
// }
// ********* end paul wenzel's modifications

On Line 362, add_cap method, adding a new capability to all blogs.

// *********** begin paul wenzel's modifications... adds a new capability
$blog_list = get_blog_list( 0, 'all' );
foreach ($blog_list AS $blog) {
	switch_to_blog($blog['blog_id']);
	$role->add_cap($newname['name']);
}
// restore_current_blog();
// $role->add_cap($newname['name']); // Original Code
// ********* end paul wenzel's modifications

Finally, at Line 446, repeat the remove_role call, which deletes roles for all blogs.

// *********** begin paul wenzel's modifications... deletes roles for all blogs
$blog_list = get_blog_list( 0, 'all' );
foreach ($blog_list AS $blog) {
	switch_to_blog($blog['blog_id']);
	remove_role($this->current);
}

// remove_role($this->current); // original code
// ********* end paul wenzel's modifications

With the above iterative loops in place, you should be able to enjoy custom roles and capabilities throughout your blog network.

Enjoy your newfound whitespace. This is confirmed to work with Safari on OSX as of this post's date. I imagine it would work in other browsers, too.
