  rvm has been installed system wide

  Be sure to add any users using rvm to the rvm group with
  
  usermod -aG rvm <username>

  You can install rubies with the following commands:

  rvm install 1.8.6
  rvm install 1.8.7
  rvm install ree
  rvm install 1.9.2

  You can then set the default system wide ruby using
 
  rvm use <version> --default
