_profile_final() not being called

I'm trying to setup an installation profile. The _profile_final() hook is not being called. It looks like this:

function medconnect_profile_final()
{
	// Define Forums
	$forums = array(
		"Reviews" 				=> "Leave good or bad reviews here of hospitals, doctors, pharmacies, prescriptions, or anything else.", 
		"General Talk" 			=> "Talk about anything.", 
		"Advice" 				=> "Give advice to others that are struggling.", 
		"Questions & Answers" 	=> "Find answers to common questions or ask one of your own."
	);
	
	foreach($forums as $name => $desc)
	{	
		$term = array('name' => $name, 'vid' => 1);
		$term['parent'] = array(variable_get('forum_default_container', 0));
		
		taxonomy_save_term($term);		
	}
		
	// Add a 'site admin' role
	db_query("INSERT INTO {role} (name) VALUES ('%s')", 'site admin');
	
	drupal_system_enable('theme', 'sky');		// enable sky theme
	variable_set('theme_default', 'sky');		// set default theme to 'sky'
	variable_set('user_pictures', 0);			// disable user profile pictures
}

None of that seems to be executed. I've also put die(); and exit; commands in there, but nothing happens. The _details and _modules hooks are being called. What am I doing wrong?
