title: IPython won't start
body: <p>I'm running Windows 7 x64. I installed the 32x verson of Python 2.7.2 and IPython 0.11 using the Windows Installers. They installed all right. I added C:\Python27 and C:\Python27\Scripts to the system envorment variables.</p>
  
  <p>When I type ipython in the command prompt I get this message:</p>
  
  <blockquote>
    <p>Traceback (most recent call last):   File
    "C:\Python27\Scripts\ipython-script.py", line 5, in 
        from pkg_resources import load_entry_point ImportError: No module named pkg_resources</p>
  </blockquote>
  
  <p>How to fix this?</p>
