On an OSX laptop with python 2.6 when I tried to pull from git and run the setup.sh the shell script terminated saying "activate: command not found." Git said it was up to date with 6b42bddc, however the contents of virtualenv/bin directory only contained pip and python 2.7 rather than all the files that should be in that directory as of 6b42bddc.
Sometimes the virtualenv directory gets messed up. We should add to HACKING.md some text about removing and rebuilding it. Developers should do this periodically.
