pass all tests

I had to roll back my ruby install from 2.1.1 to run this, and when I did so, I got this warning:

    Please be aware that you just installed a ruby that requires 2 patches just to be compiled on an up to date linux system.
    This may have known and unaccounted for security vulnerabilities.
    Please consider upgrading to ruby-2.1.1 which will have all of the latest security patches.

If you are using ruby 2.0.0 in production, might be something to look at in case you are not already aware.
