title: how to install multiple python versions on snow leopard?
body: <p>whats is the current best practice for installing multiple versions of python on snow leopard?</p>
  
  <ul>
  <li>have setup python 2.7.1 via Homebrew, very easy process, all great.</li>
  <li>but now I need to setup python 2.5 to develop an appengine project..  Initially created a new virtualenv against system python2.5 .. but finding I have all kinds of PATH issues. Seems at this point it would be better not to use Homebrew and go with a more standard setup?</li>
  </ul>
  
  <p>any thoughts ? </p>
