I agree with this...I have NEVER used PYTHONPATH.

For exactly the reason Konrad gave: An application bundle should run on 
anyone's system unchanged. The user should not have to know it is 
written in Python. So the issue is not whether The developer (Konrad, in 
this case) should use PYTHONPATH, but whether it's possible that someone 
that wants to run your application bundle is using it, and who the heck 
knows about that! A user might even have PYTHONPATH altered by some 
poorly designed application without their knowledge. The truth of the 
matter is that a lot of Python (and PYTHONPATH is part of this) was not 
designed from the start to be used to build distributable stand-along 
applications. Perhaps this will be made easier with Py3k some day, but 
in the meantime, I think it would be a great idea for Py2App to default 
to ignoring PYTHONPATH.

Would a Python interpreter embedded in a app use it? Not if I wrote that 
app!
