Installing python scripts in OS X...

Ok, so I’ve been using python on windows and linux for about 2 years now, but I just got a new macbook pro and want to do all my development on here now. Problem is, I can’t get any of my fargin’ modules to load. I’ve created a symlink into the /Library/Python/2.5/site-packages file from my local /home/Library/etc… What is the deal? In XP you drop the file into the directory with the other modules. Why isn’t it this easy on Leopard? Or am I retarded?
