How do I make Ruby 1.9 the default Ruby on Ubuntu?

Question

Is there any way, on Ubuntu 9.04, to install Ruby 1.8 as ruby1.8 (or get rid of it altogether) and have Ruby 1.9 be the default ruby?

Martin - Take a look at the following link: http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/

This is where installation of ruby is heading for ubuntu servers. This should allow you to not only switch to a ruby version when needed, but also keep gems separated based on ruby versions, etc.
