10:01 <tbuehlmann> hey there, when testing a gem, I add dependencies via add_development_dependency in mygem.gemspec and call `gemspec` in my Gemfile. now I want to test against several Gemfiles and they can't pickup the `gemspec` call from a subdirectory "gemfiles". is there any good reason to keep having dependencies in the mygem.gemspec file rather than just declare dependencies only in the Gemfiles?
