He's part of the project but he's not involved in the source control? Oops -- software sevelopment disaster in the making.
I'm in total agreement...which is why I'm trying to overhaul our development process, which involves posting to Perlmonks to see what other people do since lots of people work where they can't run the webserver on their personal machines, and have more than one worker on the project.
So please don't stop the discussion...good answers are the only way to FIX my situation.
However, to soothe your fears somewhat, he is IN the source control, just not well. (Bascially he bugs a programmer to commit his changes). It's a kludge, and annoying, and it will break sooner or later, which is why I'm trying to fix it.
