Original Answer

Not an elegant solution, but here's how I determined that I have version 2.10.1 of virtualenvwrapper installed:

$ which virtualenvwrapper.sh
/Library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh
$ cd /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/
$ ls virtualenvwrapper*
virtualenvwrapper-2.10.1-py2.7-nspkg.pth
virtualenvwrapper-2.10-1-py2.7.egg-info
