Octopress Syntax Highlighting Issue on Arch Linux

If you run Arch Linux and are trying to run rake generate on a Octopress blog, with a post that uses some code and syntax highlighting markdown over it; you will probably see this error:

/plugins/pygments_code.rb:27:in `rescue in pygments': Pygments can't parse unknown language: ruby. (RuntimeError)
