Trouble getting Ruby 2.0.0 and Rails 4.0.0 to coexist (using RVM)

I've been struggling to get the most recent versions of Ruby and Rails running on my computer (using a mid-2007 Mac, running 10.7 OSX). I originally installed with the installer at installrails.com for the purpose of completing the Rails course at onemonthrails.com.

The installer didn't include the most recent versions of Ruby/Rails, so I upgraded each one and then checked the installed versions as you can see in the retyped input/output below (SO wouldn't let me post a screenshot):

userusers-MacBook:Downloads useruser$ ruby -v
ruby 1.9.3p392 (2013-02-33 revision 39386) [x86_darwin10.8.0]
userusers-MacBook:Downloads useruser$ rails -v
Rails 4.0.2
userusers-MacBook:Downloads useruser$ rvm --default use 2.0.0
Using /usr/local/rvm/gems/ruby-2.0.0-p353
userusers-MacBook:Downloads useruser$ ruby -v
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-darwin11.4.2]
userusers-MacBook:Downloads useruser$ rails -v
Rails is not currently installed on this system. To get the latest version, simply type:

$ sudo gem install rails

What happens when I try the $ sudo gem install rails is 1 of 2 things:

1) the command appears to run, but when I go to $ rails -v after its completion, I get the same message saying Rails is not installed, or

2) the command will run successfully, $ rails -v will show I'm running Rails 4.0.0 but $ ruby -v will show I'm running Ruby 1.9.3p352. Asking it to default to Ruby 2.0.0 (via $ rvm --default 2.0.0) causes Rails to disappear again (based on the fact $ rails -v will say "Rails is not currently installed on this system").

Does anyone have an idea as to what could be the issue/how to resolve this?

If I need to provide more info or reformulate the question, let me know. This is my first post on SO and I'm new to programming as well.

When installing gems you should never use sudo because this causes many problems. What I would do it try to get a clean install by first uninstalling rails and rvm. Install homebrew which helps install gems and their dependencies by running ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)" in terminal. Then install rvm with ruby and rails at the same time by entering \curl -L https://get.rvm.io | bash -s stable --ruby --rails. This should make it easy to install whatever versions you want.
