This thread is 2 months old, but in case anybody else is looking for an alternate solution....

Edit the PHP file includes/class_bbcode.php, and in this file change:

PHP Code:

return "<a href=\"$rightlink\" target=\"_blank\">$text</a>"; 


to

PHP Code:

global $vbulletin;
if ((strpos( $rightlink, $vbulletin->options['bburl'] ) === 0) 
    || (strpos( $rightlink, $vbulletin->options['homeurl'] ) === 0))
    $target = '';
else 
    $target = 'target="_blank"';
return "<a href=\"$rightlink\" $target>$text</a>";
