I'm thinking a rake task that can fail the continuous deployment from travis might be a good fit for this? Or, maybe gems have an API they can leverage to get the version of lard?

There's an API for this under Gem, but it only shows gems loaded from installed gems, not with ruby -I like we use for development. So, instead, I'm thinking a Lard::VERSION constant that we require into the Gemspec.
