Ruby on Rails on SuSE 9.1

What is the fastest, way to get Ruby on Rails up on a SuSE 9.1 system? Almost all actual development will be done on a OS X platform. I just want the server to be WEBrick on SuSE. The version of ruby on there now is ... lists@wherever:~> ruby -v ruby 1.8.1 (2003-12-25) [i686-linux] lists@wherever:~> so the goal would be to bring ruby to 1.8.4 and install RoR. All comments welcome. john
