[CM] snd not work

[Bill Schottstaedt]

The version info says "no extension language" which means the configure
script could not find Guile, and "no graphics toolkit" which means it
couldn't find gtk.  config.log might have useful info, or you can give
configure the path directly (GUILE_CONFIG_path).  I forget how to
tell gtk where to look (it is some complicated macro in aclocal.m4 --
basically pkg-config needs to be able to find gtk).

Without either an extension language or a graphics toolkit, there's
nothing Snd can do.
