title: Run python 32-bit AND python 64-bit in separate virtual environments (homebrew install)
body: <p>I just started using homebrew, having no previous experience with package managers or virtual environments. I want to use PyGame, which only runs on 32-bit python 2.7, but keep the 64-bit version for everything else. How can I install the 32bit in a new virtual environment?</p>
  
  <p>I know that you can force python to run in 32 bit mode through 
  <code>export VERSIONER_PYTHON_PREFER_32_BIT=yes</code> but it seems unusable to set it every time i want to switch what Im working on.</p>
  
  <p>On Mac OS X 10.6.8 and Python 2.7.5</p>
  
  <p>Thanks!</p>
