Updated: July 12, 2013

The instructions below are just quick references if you know what you're doing. If you are installing RVM, Ruby, and Rails for the first time, I'd recommend following Daniel Kehoe's instructions:
http://railsapps.github.io/installing-rails.html

1. Install OS X Command Line Tools:

https://developer.apple.com/downloads/

2. Install Homebrew or MacPorts

a. Homebrew Install:
$ ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)" $ brew doctor

b. MacPorts Install via pkg:
https://distfiles.macports.org/MacPorts/MacPorts-2.1.3-10.8-MountainLion.pkg

3. Install RVM and Ruby 2.0.0-p247 as default

$ cd ~
$ echo 'gem: --no-rdoc --no-ri' >> ~/.gemrc
$ \curl -L https://get.rvm.io | bash -s stable --autolibs=enable --ruby
$ source $HOME/.rvm/scripts/rvm
$ rvm --default 2.0.0-p247

4. Install Rails 4.0.0 and Ruby 1.9.3 with Rails 3.2.13

$ gem install rails
$ gem install bundler
$ rvm install 1.9.3
$ rvm use 1.9.3
$ gem install rails
$ gem install bundler
