Incompatible with minitest gem?

When I ran rspec, I got:

Warning: you should require 'minitest/autorun' instead.

Uninstalling all minitest gems fixed this.

Thanks for posting the solution!
Frankly, I just tested it with Ruby 1.9.x. Maybe we can look into it tomorrow :-)

Try to run with minitest 4.7.5 version
