The problem I have with that, actually, is that install_venv.py in some cases winds up installing something to the system as a whole, which is not advertised and might be surprising to a user. I'm sure we could go back and forth on that though, and I totally hear the arguments on the other side. However - I do have a patch which works across ubuntu and fedora just fine. I'm going to do my best to get it upstreamed (since I would hope that M2Crypto would want a pip install of their code to work) In the mean time, figuring out the best place to put it is one of my tasks for today.
