I'm on a Bitnami Cloud Hosting account with a base stack installed for Ubuntu, but I notice that it comes default with Rails 2.3 and Ruby 1.8. I am trying to update those components without reinstalling the whole stack.
I managed to upgrade Rails to 3.2 following these instructions: http://answers.bitnami.org/questions/4125/setup-rubystack-32-from-bitnami-cloudhosting-control-panel but I have been unsuccessful in upgrading to Ruby 1.9. Using apt-get the default system Ruby was updated to 1.9 but not in the /opt/bitnami files where the stack is located. Is there an easy way to do this?
