Indeed, pt-trend didn't work at all because somehow its --quiet option was removed in the transition from Maatkit. It has been fixed and tested in 1.0 and 2.0, so it will appear in the next release for either of those series. In the meantime, a fixed version can be gotten from either the latest 1.0 or 2.0 bzr branch. Thanks for reporting this.
