I do not know if I had done something wrong beforehand, but "simply" running revdep-rebuild did not work for me - a number of packages failed to rebuild during the revdep-rebuild. They were still failing to find libpng12 during the rebuild while doing gtk-doc scan. In every case, manually unmerging the package concerned and re-emerging it was successful. It is as though it was using the scan (which needed libpng12) from the already installed package in preference to the one it had built in /var/tmp/portage/...
