[CM] Compiling snd on OSX Snow Leopard with homebrew

[Bill Schottstaedt]

Thanks very much!  I'll add that to README.Snd.  I'm amazed
(and pleased) that someone ported Motif -- if I had 2 lives,
I'd take that package and bring it into the "modern" world --
it is still better than anything else, says this grouchy old-timer
(who is now trying to move to Xfce and escape Gnome).
Please let me know of any troubles.
