Warning: require(/usr/share/mediawiki-extensions/InterwikiList/Interwikilist_body.php) [function.require]: failed to open stream: No such file or directory in /usr/share/mediawiki/includes/AutoLoader.php on line 409

Fatal error: require [function.require]: Failed opening required '/usr/share/mediawiki-extensions/InterwikiList/Interwikilist_body.php' (include_path='/var/lib/mediawiki:/var/lib/mediawiki/includes:/var/lib/mediawiki/languages:.:/usr/share/php:/usr/share/pear:/usr/share/mediawiki-extensions/include') in /usr/share/mediawiki/includes/AutoLoader.php on line 409

Line 409 is require( $filename ); in the following snippet:

I hope this can be fixed, having an interwiki list would be great.
