The gemspec is using Gollum >= 1.2.0. With 1.4.3, markup_class is not a valid parameter to the initialize method -- instead, it needs markup_classes.
I ran your test suite against this change, and everything passed. However, I'm not a Ruby developer, so please ensure this change isn't otherwise destructive before accepting.
Fixes issue #14
