[Pythonmac-SIG] py2app not happy with zope.interface

[Russell Owen]

Fixing py2app would be great, but perhaps it would suffice to document  
the problem and let the user of py2app to fix the bizarre install left  
by pip.

I'll file some kind of "complaint" against pip -- though I would not  
be at all surprised if this was a side effect of setuptools;  
easy_install has an obsession with .pth files.

I hope all this becomes a lot easier once the package metadata PEPs  
are implemented.
