I've just bumped net-wireless/bluez-utils to version 2.21. The new version depends on >=sys-apps/dbus-0.31, which is not satisfied for the hppa arch. I have therefore removed the hppa keyword from net-wireless/bluez-utils-2.21.
Fixed in cvs. bluez-stuff-0.22 is stable as well as dbus-0.50-r1. Thanks for the report.
