I just installed pip and Python via home-brew on a fresh Mac OS installation.

First of all, my pip is not installing dependencies at all - which forces me to re-run 'pip install tables' 3 times and every time it will tell me a dependency and I will install that and then rerun it again. Is this expected behavior?

Second, it does not accept the installation of Cython that it installed itself moments ago:

$ pip show cython
---
Name: Cython
Version: 0.21
Location: /usr/local/lib/python2.7/site-packages
Requires: 

But

$ pip install tables

Upgrading Cython from the upstream Git repo will resolve the problem.

 pip install --upgrade git+git://github.com/cython/cython@master
