Same for me on F15.

> Yes, I can reproduce that. It seems to be a problem in the distribute package (a.k.a. python-setuptools in Fedora). I released version 0.4.1, that uses Python's internal distutils and should install fine. I will investigate this issue and let you know when I find out what's wrong.

No, it's a problem with your monkeypatching of zipfile in 
pyp2rpmlib/archive.py(12):

# monkey patch ZipFile to behave like TarFile
ZipFile.getmembers = ZipFile.infolist
ZipFile.extractfile = ZipFile.open
ZipFile.open = ZipFile # this line is at fault here
ZipInfo.name = ZipInfo.filename

Real zipfile.ZipFile.open opens member of archive not an archive itself.
So in code above z.read(info.filename) ends up calling ZipFile instead 
of real zipfile.ZipFile.open, providing wrong aruments.
