title: pydev doesn't find python library after installation
body: <p>I'm using Django and PyDev/Eclipse. I just installed django-treebeard with <code>setup.py install</code> and it got installed in my site-packages directory <code>C:\Python26\Lib\site-packages</code>. I can successfully import it in the python shell with <code>import treebeard</code>. However PyDev complains that it cannot resolve it when I try to import it. </p>
  
  <p>Unfortunately I have no experience with PyDev and I assumed that it would automatically pick up everything in the site-packages directory but apparently it does not. What am I missing?</p>
  
  <p>thanks</p>
