title: How do I downgrade to an old version of compass using gem install?
body: <p>I've been using compass from <a href="http://compass-style.org/" rel="noreferrer">http://compass-style.org/</a> to manage my sites css for a long time. I just installed the newest version and I get a rather unpleasant error, that has as a side effect corrupted all my css files. How do I downgrade to an older version of this?</p>
  
  <p>Thanks,
  Matt</p>
