I haven't asked upstream, but my guess is that they are trying to be helpful by letting you run against new versions because this usually works out. rmagick is taking the alternative approach.

Well, it seems to me that you have to pick one of these two solutions as the sane one, or you must provide lock-step releases that refuse to build against untested new versions, which means locking in your users. Hans
