Could you provide a link please? Setting PYTHONPATH should not be
necesary, and in fact it's a very bad idea. Environment variables are
global, but Python modules may depend on the Python version, architecture,
install location... By example, you may install a 64 bits Python 3.1
version *and* a 32 bits Python 2.5 version and they both can coexist
peacefully - but an extension module compiled for the former cannot be
used in the later version. You must build a separate library for each
version, and install them in two separate directories. But since the
PYTHONPATH variable is shared by all installations, which directory should
It's best not to use PYTHONPATH at all and rely on other alternatives
(like .pth files, that are searched relative to the current Python
executable, so different versions use different configuration files)

Glad to see you could finally fix it!
