This can happen when upgrading Zsh. Zsh relies on `$FPATH` to know where to look up functions. The clue is in where it fails to load the `colors` function. ```...

There's a PR to fix this but I think it might need some discussion/pushing along, see #47

What is the current status on this one? Seems if we update Nokogiri we have to drop the pipeline that tests against ruby 1.9.3.
