It turns out that this is actually not a problem with lispbuilder-sdl-mixer,
but with the version of SDL_mixer which I compiled from source without smpeg
support. Even though I added the libsmpeg.so file afterwards, SDL_mixer
wasn't able to use it. I solved the problem by recompiling SDL_mixer from
source with smpeg present.
I am going to revert r1450 since it has no impact on whether SDL_mixer can
find smpeg or not, and may actually be inconvenient for users who don't need
mp3 support.
