PhantomJS

Install phantomjs (http://phantomjs.org)

brew has a recipe for phantomjs, but it has moved on to version 2.0.0, and we still require 1.8.2 (at newest), and we can't get that old and dirty with brew anymore.

On a Mac:

mkdir -p ~/root

wget https://phantomjs.googlecode.com/files/phantomjs-1.8.2-macosx.zip -O ~/root/phantomjs-1.8.2-macosx.zip
