title: pythonrc.py is not loading in interactive mode
body: <p>I've added a .pythonrc.py script to my home directory with the commands below:</p>
  
  <pre><code>import os
  import sys
  print 'Welcome'
  </code></pre>
  
  <p>I've confirmed that it is actually executable by running <code>python .pythonrc.py</code> and by loading the python interpreter and running <code>execfile('.pythonrc.py')</code>.  However, when I start interactive mode, it seems that the script is never being loaded.  Calls to methods in os or sys return errors that os or sys are not defined.  Has anyone seen this before?  Any suggestions?</p>
  
  <p>I'm running Python 2.6 on an Ubuntu 10 server.</p>
  
  <p>Thanks!</p>
