1: `emerge libsdl` with out any optimization ( -O ) flags using gcc-4.1.1 2: `emerge sdl-image` or `emerge sdl-sound` The second step will fail. Both builds complain that they can't find new enough libsdl because their test for it fails. Looking at respective config.log reveals that, /var/tmp/portage/sdl-image-1.2.3-r1/work/SDL_image-1.2.3/config.log: /usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../libSDL.so: undefined reference to `BlitRGBtoRGBPixelAlphaMMX3DNOW' and /var/tmp/portage/sdl-sound-1.0.1-r1/work/SDL_sound-1.0.1: /usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../libSDL.so: undefined reference to `BlitRGBtoRGBPixelAlphaMMX3DNOW' Step 2 works if libsdl is built with some optimization flag. I tested -Os and -O2 to work.

Sorry, The above has the wrong CFLAGS/CXXFLAGS that include the -O2 flag which I tried last. The failing emerge was otherwise the same sand -O2.
try libsdl-1.2.11 (works fine for me) if that fails, post the config.log from libsdl as an attachmet
