dev-util/ddd does not depend on dev-libs/elfutils, but links to libelf anyway when it is available. This confuses emerge --depclean. Reproducible: Always Steps to Reproduce: 1. emerge -1 dev-libs/elfutils 2. emerge dev-util/ddd 3. emerge -p --depclean Actual Results: emerge --depclean gives this output: * In order to avoid breakage of link level dependencies, one or more * packages will not be removed. This can be solved by rebuilding the * packages that pulled them in. * * dev-libs/elfutils-0.131-r2 pulled in by: * dev-util/ddd-3.3.12-r1 needs libelf.so.1 But rebuilding ddd does not help. Instead, removing elfutils, then rebuilding ddd helps. Expected Results: depclean should inform the user to remove elfutils, and then rebuild ddd (or use revdep-rebuild). Or the ddd source should be changed so that it does not use libelf, unless told so explicitely. I filed an upstream bug report, see the URL above. But as this seems to happen with some other packages as well, a more clear depclean explanation might help the users to understand what is going on, instead of making them build packages like ddd again and again. I get a similar message for media-libs/libcddb-1.3.2, media- sound/esound-0.2.41, sys-libs/db-4.5.20_p2-r1 and sys-libs/db-4.6.21_p4. And about esd: * media-sound/esound-0.2.41 pulled in by: * app-office/gnucash-2.2.9-r1 needs libesd.so.0 * gnome-extra/gnome-media-2.26.0-r1 needs libesd.so.0 * gnome-extra/nautilus-cd-burner-2.24.0 needs libesd.so.0 * gnome-extra/yelp-2.26.0 needs libesd.so.0 * media-libs/smpeg-0.4.4-r9 needs libesd.so.0 * media-sound/amarok-1.4.10_p20090130-r3 needs libesd.so.0 * media-sound/rhythmbox-0.11.6-r1 needs libesd.so.0 * media-sound/synaesthesia-2.4 needs libesd.so.0 * media-video/transcode-1.0.7 needs libesd.so.0 But I did not investigate this further yet.

Added Gentoo version, and reduced priority. I wonder if this bug should be filed against ddd, or if this is more a general portage thing, as it happens with other packages than ddd, too. So I changed the Component from Development to Unspecified.
libelf is only used on PowerPC, in other cases unnecessary libelf link dep should be dropped when --as-needed is passed as an argument for linker (which is from now on enabled by default). I've added elfutils dependency for ppc and ppc64 to make debugging more useful there. Thanks for reporting.
