That solved the problem!  Thanks Takashi!  Now that I've gotten the 
software to compile correctly and I'm able to interact with the audio 
hardware using alsamixer, I tried to run the speaker-test and now I'm 
getting the error "ALSA lib 
pcm_direct.c:1616:(snd1_pcm_direct_parse_open_conf) The field ipc_gid 
must be a valid group (create group audio)" which I can see is a problem 
with the absence of the 'audio' group on the distro.  Is there a way I 
can configure alsa to use a different group other than 'audio'?

Thanks,
Dave
