## How to install Rabbit with Homebrew on Mac OS X

This document describes how to install Rabbit with Homebrew and RubyGems on Mac OS X.

### Requirements

- An Intel CPU
- OS X Leopard or higher
- Xcode with X11

### Install Homebrew

    $ ruby -e "$(curl -fsS http://gist.github.com/raw/323731/install_homebrew.rb)"

Then add /usr/local/bin to your PATH.

### Install Softwares Rabbit Needs (brew install)

Change files in /usr/local/Library/Formula/*.rb as follows. Then exec "brew install".

#### /usr/local/Library/Formula/pango.rb

    require 'formula'

    class Pango < Formula

      depends_on 'pkg-config' => :build
      depends_on 'glib'

      fails_with_llvm "Undefined symbols when linking", :build => "2326"

      if MacOS.leopard?
        depends_on 'fontconfig' # Leopard's fontconfig is too old.
        depends_on 'cairo' # Leopard doesn't come with Cairo.
      end
