title: What does this error mean: invalid ELF header
body: <p>I'm getting an <code>IMPORT ERROR</code> with the following error message in Django debug mode <code>/usr/local/lib/python2.6/dist-packages/lxml-2.3-py2.6-win32.egg/lxml/objectify.pyd: invalid ELF header</code></p>
  
  <p>What does this mean and how do I fix it? Google is revealing not very much at the moment. This error is coming from this <a href="https://github.com/tschellenbach/DjangoOpenInviter" rel="noreferrer">package</a> I am using in my Django app</p>
  
  <p><strong>Update</strong>
  I'm using ubuntu and Python2.6</p>
