That is okay. Happens here as well.

This looks more like a problem with SDL or ALSA.  Which backend are you
using (dpkg -l "libsdl1.2debian-*")?  Does this trivial program work:

--8<---------------cut here---------------start------------->8---
#include <SDL/SDL.h>
#include <stdio.h>

int main(void)
{
        int ret = SDL_InitSubSystem(SDL_INIT_AUDIO);
        if (ret == -1)
                puts("SDL_InitSubSystem failed.");
        puts("SDL_InitSubSystem(SDL_INIT_AUDIO) done.");
        return 0;
}
--8<---------------cut here---------------end--------------->8---

Building with "gcc -o sdl-test -lSDL sdl.test.c" should work once you
have installed libsdl1.2-dev.

Good, then it at least seems not to depend on ~/.simutrans.
