what did I wrong ? I downloaded the extension and have it in to the intersection folder. After adding the load entry to the config file following Error occured:
Notice: Use of undefined constant __DIR__ - assumed '__DIR__' in /var/apache2/2.2/htdocs/mediawiki-1.18.1/extensions/intersection/DynamicPageList.php on line 51
Warning: include(__DIR__/DynamicPageList.i18n.php) [function.include]: failed to open stream: No such file or directory in /var/apache2/2.2/htdocs/mediawiki-1.18.1/includes/LocalisationCache.php on line 408

What should I do ?
