well if you dont have vbulletin it might be tough getting that to work but if you get a blank page its no doubt because of the need to uncomment and fill out the mysql database info and lines. Do realize I can not support that file not installed as it is supported to be installed. I can give you some hints. Like in whatever php file your including it after editing inc_features.php with the right database info etc you edit whatever php file you want to include it in and maybe put this changing to your right paths etc
You will no doubt need to hack up that file to match styles etc
