Update II Problem Solved but Why? This has been the biggest headache ever. My problem is solved, however I have no clue how I accomplished this task. Plus the following results make no sense. My .profile path (/usr/local/bin) is different than the path that is currently working (/usr/bin/). The working path suddenly appeared after I closed terminal in OSX snow leopard. What is going on here?
Here is the working paths and confusing .profile file:
$ rails -v
Rails 3.0.0.beta
$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
$ gem -v
1.3.6
$ whereis ruby
/usr/bin/ruby
$ whereis rails
/usr/bin/rails
$ whereis gem
/usr/bin/gem
$ which gem
/usr/bin/gem
$ which ruby
/usr/bin/ruby
$ which rails
/usr/bin/rails
$ mate ~/.profile
.profile file:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"
if [[ -s /Users/justinz/.rvm/scripts/rvm ]] ; then source /Users/justinz/.rvm/scripts/rvm ; fi
Update I notice that which ruby and whereis ruby are different locations
which ruby
/opt/local/bin/ruby
whereis ruby
/usr/bin/ruby
I recently upgraded ruby to ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10] and I think I broke rails. When I attempt to load rails. I get an odd message. Please help!

Have you looked into the Ruby Version Manager or rvm ( http://rvm.beginrescueend.com/ ). I know that it runs on linux and Mac OS X.
Basically it is a tool that manages different versions of ruby and all its associated “pieces”. I was having similar problems when a friend recommend I try it, and it solved it for me.
