cPanel upgrade to run ruby 1.9.2, and latest rails

Hi there, I currently have a lamp setup with Cpanel/WHM for the customers, but I want to be able to host ruby 1.9.2 rather than 1.8.7. To do this I was following the below guide: [login to view URL] Ran into problems with installing the passenger apache module, so thought I'd outsource the work. The setup should be: users can use rvm to switch ruby versions install their own gems use the rails function to generate new apps. I understand that phusion only supports one ruby version at a time, so the first option can be removed. The server itself is running on cloudlinux.
