While installing Tahoe http://allmydata.org/trac/tahoe I ran into problems after I did a 'sudo python setup.py install'. It compiled and installed fine, and it ran fine from within the source tree (./bin/tahoe), but when I attempted to use the system-wide tahoe executable, it failed on importing two libraries tahoe installed (allmydata and pyutils). Eventually I discovered it was because the libraries were indeed in site-packages/, but they didn't have permissions allowing a mere user to read or use them. Which is a bad thing.

This is a known issue upstream, we'll wait for them to work it out. http://bugs.python.org/setuptools/issue6 Note: This bug doesn't affect ebuilds that use setuptools.
