That's why I suggested using "--changed-deps": It doesn't rebuild packages that provide the library itself and have already been built after the library provider... OTOH, it doesn't check binary dependence, just what is written into the ebuilds itself. But it should work most of the time. A combination of two emerge invocations may work, too: # emerge -DNua world --changed-deps # emerge -1a @preserved-rebuild --changed-deps This also worked well for me when I did the gcc upgrade. But I think the need to use changed-deps to rebuild dependers should be considered a bug and be reported. Portage has support for sub-slot dependencies to describe such binary breakage during upgrades and automatically rebuild the dependers. -- Regards, Kai Replies to list-only preferred.
