method_missing: `foo` exception emitted from Markaby builder code

[orospakr]

Host machine is Ubuntu 12.10.

This failure happens regardless of my use of bundler or a system-wide install of Stasis as per the documentation on http://stasis.me.

This seems to happen when I install Stasis' dependencies into my app with Bundler, and have Bundler install the gems into a path inside my app. Even if ignore the bundle directory (that's what I typically name it) in controller.rb it continues to fail.

However, having bundler install my gems somewhere outside my site's directory clears it up.
