Ironfan broken under ruby > 2.0

[andyleclair]

A simple run of the specs will show (after swapping ruby-debug for byebug in the Gemfile) that Ironfan doesn't even run a little under ruby 2.1.2.

*[master][~/src/ironfan]$ bundle exec rake spec

This behavior can be replicated in versions of ironfan going back to 4.5.0 (I didn't go any further back).

I tried to check out Gorillib to see what was going on there, however, I couldn't run the Gorillib specs under 2.1.2 either.

I also tried to run the specs under ruby 2.0.0-p481, p195, and p247 and none worked.

It seems that you have serious compatibility issues with ruby 2.x. You should at least mention that it won't run under ruby > 2.0 on the readme, or better yet, fix it.

I confirm that ironfan doesn't work with ruby >= 2.0.0 , I already had the problem, and it took me long time to understand it was the ruby version that caused the problem. The error message isn't clear at all.
