mkvirtualenv ImportError: No module named stevedore

I've got a Mac which has python installed and virtualenvwrapper installed. I'm trying to create a new environment by running: ``` mkvirtualenv Test ``` To which I get the following error: ``` New python executable in /Users/sidharthnayyar/.virtualenvs/Test/bin/python Installing setuptools, pip, wheel...done.

If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python and that PATH is set properly. ``` Curious and curiouser. Any suggestions on what's going wrong and how to fix this? Thanks Sidharth
