what did you do to fix it?
as noted in info you need xorg, oss or alsa setup properly, and accelerated graphics for smooth play (ati&nvidia drivers for example)
if you are receiving "unable to open audio, failed to load ... " error it means you don't have an audio device setup properly to fix it you need to load OSS or ALSA and setup if required.
developers of dreamchess should fix this rubbish problem why would i need a sound device to play a 3d game ?
