title: How to revert back to the default Ruby install on Mac OSX Lion Server
body: <p>I did an install of Redmine on my OSX Lion Server following the install guide on the Redmine website. There it told me to update/install some RubyGems. The install of Redmine went fine but the procedure killed my Profile Manager and Wiki Service.</p>
  
  <p>Looking around on the web led me to the Apple Support web page <a href="http://support.apple.com/kb/TS4042" rel="nofollow">http://support.apple.com/kb/TS4042</a></p>
  
  <p>Basically it says not to update or install Ruby Gems because it will cause problems but it does not give a solution if you already did update or install any Ruby Gem.</p>
  
  <p>Is there a way to revert back to the default Ruby install on OSX Lion Server (10.7.3) without a complete reinstall of the system?</p>
