The gnome-extra/nautilus-cd-burner-2.10.1.ebuild uses "cdr" in the RDEPEND section (but not in the DEPEND section). It *isn't* listed in the IUSE. This might be a misunderstanding of IUSE on my part, but the ebuild(5) man page isn't clear on it, so perhaps this a documentation bug instead :-) Just wondering... Phil
Most definitively a bug. All USE flags used inside an ebuild should be listed in IUSE. Thanks for reporting this. It has been fixed now.
