>>> sys.path.append('/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/PyObjC')

Fixes it, I am going to poke at the virtualenv source to see if I can fix it.

Did it “Just Work”?

I've tried creating environments with both version 0.9.2 and from SVN with the clean python install from Leopard and none of my environments are references the location of the globally installed packages. I just get absolutely clean environments every time without the PyObjC stuff!

I'm quite new at this ;) do you have any ideas?
thx
