It still fails for me and I can explain why. Fail log is attached.
The SourceForge URL is longer than the same .egg URL for PyPI package.
That's why setuptools choses SF instead of PyPI. But because SF URL
doesn't end with .egg setuptools fails to install it. Seems like
setuptools is crawled with roaches. =)

If the Python was the only code inside - that'd be acceptable, but it
seems like the proper fix lies in setuptools AI code.
Thanks for support.
