I have doubt here... i guess both are different sw... but look... [1] yum install graphviz-ruby vs [2] gem install ruby-graphviz should i start packaging the 2nd, what about the first? (confused)

This appeared on adopting rubygem-state_machine (testing it): $ ruby unit/state_test.rb Skipping GraphViz StateMachine::State tests. `gem install ruby-graphviz` >= v0.9.0 and try again. ... Then i tried the existing rpm [1] without luck for state_machine, the i tried the gem version [2], which fixes the output warning.

You can create "rubygem-ruby-graphviz" srpm from ruby-graphviz(-0.9.16).gem and import it into Fedora if you want to enable all tests.
