Doug,

you need to add "/usr/local/bin" to your PATH variable. It's apparent  
from this question that you don't understand some of the basics of  
OSX's UNIX shell behavior. Here's a link [1] to a set of basic UNIX  
tutorials which will give you a nice foundation for working in a  
shell environment going forward.

In the meantime, fire up Terminal.app and do the following:

1. cd $HOME

2. echo 'PATH=/usr/local/bin:$PATH' >> .profile

3. echo 'export PATH' >> .profile

Make sure you use single quotes instead of double quotes!

Quit Terminal.app and then reopen it. At the shell prompt type 'which  
ruby' to confirm it returns '/usr/local/bin/ruby' to you.
