	None at all... I've attached a patch that should do this
properly.  It will look for AUDIOSERVER then DISPLAY.  If neither of these
are set, then :0 is assumed.  Of course specifying the port on the command
line takes precedence as usual.

	Let me know if it actually works ;-)

	Supposedly, something like 'make install DESTDIR=/some/other/dir' 
will do the trick, though I've never tried this myself.

	Yeah... Isn't that fun :-| Theoretically, you can do this with the
standard X env (from x.org)  by defining 'HasGcc2' in your systems
site.def file, and then hoping the proper CFLAGS et. al. are setup in
sun.cf.

	Of course a better way would be to use autoconf in NAS.  But, that
too is another can of worms ;-)
