Install xcode 4

App store http://itunes.apple.com/us/app/xcode/id448457090?mt=12) The download/install takes awhile so start it first. When it finishes downloading you will still need to run it to complete installation.

# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).

Get Mountain Lion and Homebrew to Be Happy

1) Install XCode 4.4 into /Applications

Get it from http://developer.apple.com. You will not be able to submit apps to any stores using this XCode version, so turn away if that is something you might want to do.

2) Install Command Line Tools

In XCode's Preferences > Downloads you can install command line tools.
