[ocamlsdl-user] Build problems on OS X

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I cannot build/run any OCamlSDL programs on OS X 10.5. I built SDL and
SDL_mixer with straight configure/make/make install.

If I try to make a new top-level:

$ ocamlmktop -I +sdl -custom -o ocamlsdl bigarray.cma sdl.cma

Am willing to help debug this (though I'm new enough to not know how
to start on my own). I'm trying to get sample-level access to my sound
card, and OCamlSDL seemed my best bet.
