virtualenv gives me command not found on this machine, but homebrew isn't noticing it as the name of a package either, so I can't install it. sudo pip install --upgrade distribute gives me an error and a weird traceback.

Now I'm getting a different annoying error when I try to rerun sudo pip install --upgrade distribute. Since the installer uses this command, it also causes the installer to fail (now in a different way).

Also, this link might help: https://gist.github.com/1208841

I tried some stuff in there though, and it gave me the issues I mentioned above (this is all on Jake's machine, not mine).

Idea from @kristenmills: Try which pip and which python, make sure they're int he same place.
