[CM] newbie - how to build and run

[adam]

Installed the libmotif-dev package. Get a new make error as below.

Perhaps this is X libs missing. Perhaps I should apt-get build-dep snd 
just to get all X sources? 

gcc -c -DSCRIPTS_DIR=\"/usr/local/share/snd\"  -O2 -I. -g -O2      snd-find.c
gcc -c -DSCRIPTS_DIR=\"/usr/local/share/snd\"  -O2 -I. -g -O2      snd-snd.c
gcc -c -DSCRIPTS_DIR=\"/usr/local/share/snd\"  -O2 -I. -g -O2      snd-help.c
