After the recent hard masking of the emul-linux-x86-* libraries I followed the upgrade procedure of; uninstalling all said libraries, adding =app-emulation/emul-linux-x86-xlibs-20130224-r1 to my package unmask file, putting 'ABI_X86="64 32" in my make.conf file, then rebuilding the entire world.

Created attachment 400640 [details] Emerge log of libsdl2 Here is the build log of the failed package.
First of all, ABI_X86="64 32" wasn't really a good suggestion. How exactly does the mentioned header differ between arches ?

I am unfamiliar with how the system builds both the 32 and 64 bit versions so where would the work dir's be rather than the standard singular one in /var/tmp/portage?
Well, for you it will be under /var/tmp/portage, just not in image/. Just look at dirs in /var/tmp/portage/media-libs/libsdl2-2.0.3-r200/ - should be semi-obvious which dirs are the build dirs.
Found it. According to diff this is the only thing different with the package SDL_config.h file. Hydrascale work # diff /var/tmp/portage/media-libs/libsdl2-2.0.3-r200/work/SDL2-2.0.3-abi_x86_32.x86/include/SDL_config.h /var/tmp/portage/media-libs/libsdl2-2.0.3-r200/work/SDL2-2.0.3-abi_x86_64.amd64/include/SDL_config.h 219c219 < /* #undef SDL_AUDIO_DRIVER_FUSIONSOUND */ --- > #define SDL_AUDIO_DRIVER_FUSIONSOUND 1 And as you can see fusionsound is toggled on.

OK, so the cause of the problem is clear - it's a combination between libSDL designand neither DirectFB nor FusionSound having a multilib ebuild...
I would like to add, now that I have had time to test it. Libsdl2 builds with abi_x86_32 enabled if you disable fusionsound
masked the fusionsound use flag. If any of the deps ever gain multilib support, please open a new bug.
