Are you trying to run it on a PPC ?

Ah, at last a new error ! ;)

Hmm, I'm not sure what the problem might be. Have you tried commenting
out the relevant code in fft-menu.scm ? See what happens when you do

Did you compile Snd yourself ? If so, the --with-ladspa configuration
flag won't work if you don't already have LADSPA and its plugin sets
installed beforehand.

Alas, I've done nothing to accomodate the GTK build so I can't say much
about it (other than that I prefer the Motif build anyway). AFAIK none
of my widget work has gone into the GTK stuff yet, and I probably won't
do it (too many other commitments).

LADSPA plugins can be dynamically loaded into Snd via the Listener, but
you won't get any auto-generated GUI. The LADSPA plugins I've prepared
for Snd are all hard-coded into their widgets. Yes, that's very
inefficient, and no, I am not a programmer. If someone with real skills
would like to undertake the task I'd gladly defer...

What sound driver are you using ? If ALSA you may only need to adjust
the volume. OTOH you should also have a GUS patch set installed in a
path recognized by TiMidity else you'll get no sound
