When I say PATH I mean the PATH environment variable.

sys.path is a side-effect of which interpreter was run, not the cause 
of it.  By the time sys.path even exists, you're already running 
Python, so how could that be relevant?

I've said this to you before, those folders are *NOT IN ANY WAY 
SPECIAL*.  Moving stuff around on the filesystem isn't going to do 
anything (except break stuff).

Read 
<http://svn.red-bean.com/pyobjc/trunk/pyobjc/Doc/Xcode-Templates.html>, 
hopefully you'll figure it out.  If not, search the archives or ask the 
Wing folk.  I don't really have time right now to explain in more 
detail than I already have.
