title: pylint not recognizing some of the standard library
body: <p>I'm using pylint + pydev, with python 2.6.
  I have a module with just this line of code</p>
  
  <pre><code>from email import Message
  </code></pre>
  
  <p>Now when I try to run this module it runs fine. But pylint reports an error:</p>
  
  <pre><code>ID: E0611 No name 'Message' in module 'email'
  </code></pre>
  
  <p>Although it exists...
  Any idea why?</p>
