I found that revdep-rebuild wanted to keep re-building sys-power/cpufreqd-2.2.1 because of a faulty .la file which referenced a library in the (now deleted because intentionally temporary) build directory. This is documented in #268701. Even though no other packages were spotlighted by revdep-rebuild, I then grep'ed the .la files in /usr/lib to search for other examples of references to libraries in temporary build directories, then matching the resulting files to the packages that own them. This is what I found: # equery belongs /usr/lib/libggzcore.la * Searching for /usr/lib/libggzcore.la ... dev-games/ggz-client-libs-0.0.14.1 (/usr/lib/libggzcore.la) # equery belongs /usr/lib/libggz.la * Searching for /usr/lib/libggz.la ... dev-games/libggz-0.0.14.1 (/usr/lib/libggz.la) # equery belongs /usr/lib/libggzmod.la * Searching for /usr/lib/libggzmod.la ... dev-games/ggz-client-libs-0.0.14.1 (/usr/lib/libggzmod.la) # equery belongs /usr/lib/libxorsa.la * Searching for /usr/lib/libxorsa.la ... sci-astronomy/orsa-0.7.0 (/usr/lib/libxorsa.la) # equery belongs /usr/lib/libvisual-0.4.la * Searching for /usr/lib/libvisual-0.4.la ... media-libs/libvisual-0.4.0-r1 (/usr/lib/libvisual-0.4.la) # equery belongs /usr/lib/libexiv2.la * Searching for /usr/lib/libexiv2.la ... media-gfx/exiv2-0.18.1 (/usr/lib/libexiv2.la) For now I have manually edited the .la files, but I guess that they ought to be fixed at some point (always assuming they are required anyway).
You want dev-util/lafilefixer.
Reopen this bug if dev-util/lafilefixer doesn't fix your problem.
