Installing RVM on Ubuntu

Excellent notes by Chris Irish to install RVM on Ubuntu.

One extra thing to mention (as this has caused me some issues) is that when using rvm, you should avoid installing jruby as the first ruby, as it looks like it tries to use it to compile the following ones — causing troubles to install 1.9.2-head. If you have installed jruby as the first ruby, you can delete it with rvm remove, then install MRI, or ree, and only then install jruby.

(It is very likely that this is caused by the fact my “system” ruby was actually a ruby I had compiled myself…)
