Hi Michael,

I would recommend you to install those bits in your home directory. The
process would look something like:

1. Download ruby sources or checkout the svn repository. Compile and
install in $HOME/local.

2. Change your $PATH to ensure your shell finds the ruby you just 
installed.

3. Install rubygems

4. Install whatever gems you want...

5. Install mysql in your $HOME/local. That's a little bit trickier but there
are many howtos/tutorials out there. This is pretty good:

You are now good to go. If you want to run any ruby code with the preinstalled
version of ruby just use the full fs path (/usr/bin/ruby ...).
