If mysql2 is not installed I see the following error on my hardened ~amd64 machine. The error vanishes when I install mysql2 manually. * Running test phase for ruby19 ... /usr/lib64/ruby/gems/1.9.1/gems/bundler-1.3.6/lib/bundler/resolver.rb:296:in `resolve': Could not find gem 'mysql2 (>= 0.3.10) ruby' in the gems available on this machine. (Bundler::GemNotFound)
We should probably fix this by cleaning up the Gemfile further.
This should now be fixed.
