Ruby on Rails

Hello, I'm new to Ruby and unix/linux development (although been
building .net apps for years).

I've almost completed my trek to install Rails ... looks like I have one
final hurdle. After installing rails I try the 'rails -v' command and
it fails. Any help here would be deeply appreciated.

Here's the output from my bash session:

bash-3.2$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0]
bash-3.2$ which gem

bash-3.2$ sudo gem update --system

== 1.8.11 / 2011-10-03

* Bug fix:
* Deprecate was moved to Gem::Deprecate to stop polluting the
top-level
namespace.
