Pip, virtualenv and github on the mac

Apologia

This page is incomplete. Jeremy is working on it.

Notes

• Intel Macs only.
• Two recipe sets: XCode+Homebrew and EasyInstall+setup.py
• Virtualenv and virtualenvwrapper need some environment changes, e.g., .bashrc.
• DON'T CHANGE THE DEFAULT PYTHON IF YOU VALUE YOUR LIFE. Python 3.0 is nice, but not that nice.
