fumblr fails to install on OS X Yosemite with Ruby 2.0

[pauljonescodes]

First it was because nokogiri failed to install. Stack trace:

An error occurred while installing nokogiri (1.4.4), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.4.4'` succeeds before bundling.

But I managed to install it using this SO post.

But then padrino fails to start:

Any advice or resolution much appreciated, fumblr is exactly what I'm looking for, thanks for making it.
