Shell Script To Automate Ruby on Rails Installation on Mac OS X 10.8.3 Mountain Lion

When setting up a Ruby development environment on Mac OS X 10.8.3 I ran into plenty of errors and incompatibilities.  I wrote a shell script to automate the process.  Feel free to copy and paste the script below into a executable file to automate the roll out of Ruby on Mac OS X for your developers.  This script should be run with the user's login credentials.  Sudo or root are not needed.  

The script installs the following versions of software required to start writing Ruby on Rails code today!

Versions as of April 2013
  • Homebrew 0.9.4
  • RVM 1.19.5
  • Ruby 2.0.0p0 rev 39474
  • Rails 3.2.13
  • Git 1.8.2.1
  • MySQL 5.5.27
  • Xcode 4.6.1 and Xcode Command Line Tools (get it from the Apple Store for free)

Brew and RVM will also install all the dependencies you need.  Copy and paste everything between ---BEGIN--- and ---END---
