[Python-modules-team] Bug#655584: python-virtualenv: Created virtualenvs don't search for packages in /usr/lib/pymodules

[Andreas Kloeckner]

Package: python-virtualenv
Version: 1.7-1
Severity: important

Dear Maintainer,

Consider the following situation:

$ which python                                                                                                                                                              andreas at ding 9:47

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy

I would have expected the created virtualenv to find numpy, but it
doesn't. I've traced this back to /usr/lib/pymodules not being part of
sys.path in the created virtualenv:

>>> import sys; print [x for x in sys.path if 'pymodules' in x]
[]

Thanks,
Andreas
