This is a little over my head, but for anyone trying to build it, the most recent source is here:
http://vgm.mdscene.net/forum/viewtopic.php?t=110

and it looks like it's supposed to be built with the MAME tool set outlined here:
http://advancemame.sourceforge.net/doc-build.html

So if you've got a working scratchbox (I currently don't) go for it.
