Not sure how that ever passed code review. That alone would probably fix the issue, but I'm not sure as I can't tell you why their call of #name returns another dep. Couple that with a very sketchy implementation: def add_load_paths self.class.add_frozen_gem_path return if @loaded || @load_paths_added if framework_gem? @load_paths_added = @loaded = @frozen = true return end gem self @spec = Gem.loaded_specs[name] @frozen = @spec.loaded_from.include?(self.class.unpacked_path) if @spec @load_paths_added = true rescue Gem::LoadError end `gem self` where self is a GemDependency (a subclass of our Gem::Dependency) just doesn't make sense. I'm not sure how this ever worked and it is possible it never did given that completely blithe rescue at the bottom... ---------------------------------------------------------------------- You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=575&aid=29188&group_id=126 _______________________________________________ Rubygems-developers mailing list http://rubyforge.org/projects/rubygems Rubygems-developers@rubyforge.org http://rubyforge.org/mailman/listinfo/rubygems-developers
