During 'emerge -auv' and friends, gnome-base/libbonoboui-2.24.5 is slated for upgrade. After rounds of revdep-rebuild, lafilefixer, and re-merge of libbonoboui's dependencies, package still fails to build with: [...] /libbonobo-activation.so /usr/lib64/libORBitCosNaming-2.so -ldl

lafilefixer doesn't help with this case, but it's indeed a problem with .la files you have installed I guess you missed the news item in Portage: http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-news/2011/2011-10-15-libpng15/2011-10-15-libpng15.en.txt?revision=57&view=markup *** This bug has been marked as a duplicate of bug 319101 ***
