ExecJS and could not find a JavaScript runtime
I'm trying to use the Mongoid / Devise Rails 3.1 template (Mongoid and Devise), and I keep getting an error stating ExecJS cannot find a JavaScript runtime. Fair enough when I didn't have any installed, but I've tried installing Node.js, Mustang and the Ruby Racer, but nothing is working.

Rails: Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)
I'm using Rails 3.1.1 on Ruby 1.8.7 and get presented with a 'Ruby (Rack) application could not be started error' from PhusionPassenger. It states that it 'Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)'. Searching for this on Dreamhost's wiki has suggested a solution to install 'therubyracer' gem.
