You need to declare $vbulletin as global, or else use $this->registry instead, like $this->registry->options['drcpo_sup_pb_perm'].

Yeah, I know. That's one issue with the hook system. What you can do and what variables are there has to do with where they decided to put the hook. Eventually you get to what's goign on around the "popular" hooks, but I think the only way to really be able to write plugins its to set up the code so you can search all the files (I use notepad++ on my PC) and search for the hook name, and look at the code there.
