Default Enabling plugin causes whitescreen

I have a small PHP program, http://www.netbuilders.org/showlinks.php, which acts as a link rotator.

I want to include it in my vBulletin templates, so I created a plugin called showlinks.

I used global_start as the hook location and used this as my plugin PHP code:
Code:
ob_start();
include('/usr/local/www/data/netbuilders.org/showlinks.php');
$nblinks = ob_get_contents();
ob_end_clean();
When I enable the plugin, the forum stops working. It will only display a blank white screen until I disable the plugin again.

I have read these two documents and they are not providing me with any usable clues:Has anyone seen vBulletin do this before?

When the whitescreen behavior is occurring, this error message fills my Apache logs: "PHP Fatal error: Call to a member function query_read_slave() on a non-object in /usr/local/www/data/netbuilders.org/includes/functions.php on line 4819."

The code around line 4819 is:
Code:
$ismod_all = $vbulletin->db->query_read_slave("
                                SELECT forumid, moderatorid, permissions, permissions2
                                FROM " . TABLE_PREFIX . "moderator
                                WHERE userid = $userid" . (!$issupermod ? ' AND forumid != -1' : '')
                        );
Any ideas?
