title: How to add something to PYTHONPATH?
body: <p>I downloaded a package (called pysolr 2.0.15) to my computer to be used with Haystack. The instructions asks me to add pysolr to my PYTHONPATH.</p>
  
  <p>What exactly does that mean? After extracting the pysolr files, I ran the command python setup.py install and that's about it. What did that do and do I need to do anything else?</p>
  
  <p>Thanks for the help!</p>
