Not sure about this theory - I can reproduce the version mismatch with an almost plain Python 2.5 installation - especially it is reproducable within a virtualenv --no-site-package environment. On the other hand: I can not reproduce this error on my Linux box with a Python 2.4 installation with pretty large site-packages dir :-> > > Setuptools loads packages and puts them into the environment as it finds > them.
