This seems to happen only when portaudio is installed. Uninstall
portaudio and alienarena starts up. I'm not sure exactly what is
going on here, but it seems that alienarena is both trying to dlopen
libopenal, and is linked against it. Check it:
ldd /usr/libexec/alienarena | grep -F openal
My guess (and it is just a guess) is that this is triggering multiple
initializations of portaudio. Try this patch:
diff -dur alienarena-7.32.ORIG/source/Makefile alienarena-7.32/source/Makefile
