How did you install zope.interface? Basically which easy_install or pip command-line did you use to install?

I guess the nspkg.pth ensures that zope.interface can be imported without an __init__ file and py2app doesn't parse those files (or doesn't understand how to do so). If I can reproduce the problem I can  (and will) fix it.
