Description of problem: ruby-2.1.6 ships with rubygems 2.2.3, yet the rubygems package is still at 2.2.2. Version-Release number of selected component (if applicable): 2.2.2 101.fc21
Does it cause any practical issues? I am not aware of any ...
Ahh, actually ruby ships RubyGems 2.2.3 but the bundled package does not reflect it. That is definitely wrong.
