    I have this too and it's epidemic if you Google for it. I have virtualenv 12.0.7 on Mac with Python 2.6. Python 2.7 acts the same. "pip install --upgrade virtualenv==1.11.2" does not fix the problem.

    Aha! Uninstall a global "/usr/local/bin/tox" executable I had that was interfering with the tox I'd installed in my virtualenv.
