title: How to uninstall Ruby from /usr/local?
body: <p>Everything was working fine , until we decided to upgrade ruby to 1.8.7 from 1.8.6, and thats when all hell broke loose. When we compiled Ruby 1.8.7 from source it got installed into /usr/local/bin and Ruby 1.8.6 stayed in /usr/bin. 
  Currently, we've uninstalled ruby 1.8.6 and by some stroke we deleted the ruby 1.8.7 files from /usr/local.</p>
  
  <p>when we try "which ruby" it points to /usr/local.
  If anybody could help us out what we need to do get back on track , we would be very grateful.and also any idea how we can uninstall ruby from /usr/local. 
  we tried yum remove ruby , which removed ruby from /usr/bin.Thanks and Cheers ! </p>
