title: Error while executing "paster shell example.ini" in reddit.com
body: <p>Friends!!! I am frustated since last five days working on implementing
  reddit.com on a ubuntu 9.10 machine.</p>
  
  <p>Yes, I know that reddit.com has been tested on ubuntu intrepid.  But
  now i want to install it on U9.10</p>
  
  <p>I have installed postgresql database, created user copied the files,
  and installed all the dependencies.</p>
  
  <p>Everything is installed perfectly as described in the document
  <a href="http://code.reddit.com/wiki/RedditStartToFinishIntrepid" rel="nofollow noreferrer">http://code.reddit.com/wiki/RedditStartToFinishIntrepid</a>
  until the line:</p>
  
  <blockquote>
    <p>$ paster shell example.ini</p>
  </blockquote>
  
  <p>this line gives me a error and i couldnt figure out where the problem
  lies.</p>
