Title: Psych compatibility

This drops the enforced Syck. If the YAML is properly formated, there is no need for Syck. Syck was long deprecated and now removed from Ruby 2.0. Not sure if some of your documentation should not be updated in similar manner as the failing .spec.

BTW, I am going to apply this to Fedora 19/Rawhide.
