Thor Error when running migrations

Hi -

I have tried to start with the gamification github repo to run a "hello world" version of the gamification gem / app.I figured that it was easier to clone the gamification repo and follow the instructions in the readme file.

I thought it was my environment that was the issue and perhaps still is, but I tried on a "clean box" via https://www.nitrous.io and spent a few hours on my local to get gamification to work without any luck.

I keep getting the following:

NameError: uninitialized constant Thor::Base

Are there any documents or Noob tutorials that show the hyperoslo/gamification solution working by way of a demo installation or a 'getting started from scratch guide'? Perhaps showing how to build from some solid tutorials such as Hartel's Sample_App, etc?

I am not necessarily seeking trouble-shooting advice for my specific environment per se, but more or less seeking a successful example from which to follow.

Thanks!
