title: Unresolved import, urllib2 error in Eclipse
body: <p>I just installed PyDev in Eclipse and the following line fails on me:</p>
  
  <pre><code>import urllib2
  </code></pre>
  
  <p>So, to verify, i opened python in interpreter mode(outside of Eclipse) and tried to import urllib2, it seems to work. </p>
  
  <p>I tried <code>import sys</code> in Eclipse and that seems to be work fine. </p>
  
  <p>I think urllib2 comes packaged with standard Python installation. Is there an explicit path i need to set in my Eclipse? </p>
