 ## 2. Ruby
 
 The use of ruby version managers such as [RVM](http://rvm.io/), [rbenv](https://github.com/sstephenson/rbenv) or [chruby](https://github.com/postmodern/chruby) with GitLab in production frequently leads to hard to diagnose problems. Version managers are not supported and we stronly advise everyone to follow the instructions below to use a system ruby.
 
-Remove the old Ruby 1.8 if present:
+Remove the old Ruby 1.8 package if present. Gitlab 6.7 only supports the Ruby 2.0.x release series:
 
     yum remove ruby
 
+Remove any other Ruby build if it is still present:

+    make uninstall
