My advice? Remove 1.9.0 and just use the Ruby 1.8.6 that is already 
installed on your system. 1.9.0 is not "up to date," it's a developer's 
version of Ruby that has bugs and undocumented features. All the books 
you'll buy, and 99% of the web sites, describe 1.8.6, not 1.9.0, so all 
you'll do is confuse yourself. Dump 1.9.0 until you're a Ruby expert.

Also, buy a book about OS X that describes how to use the shell and Unix 
commands. You can't use Ruby effectively on OS X by clicking on things.
