I don't think the patch does exactly that. It reshuffles dependencies so
that local ones are looked at first. That includes *any* local
dependency, of which there can be several. Probably what's going to
happen is that it's going to pick the latest local dependency that
satisfies gem spec. I don't think this is what you want, however...
