That was exactly it.

It looks like I applied the patch twice.
It looks like I applied the patch twice.

Started again from a clean CVS, built it, and it runs w/o curses, no problem.

Then decided to try it without the --disable-curses switch. Configured just 
fine (configure was able to find initscr and resizeterm). 

But:
gmake[3]: Entering directory `/usr/home/ken/simulavr/src/disp'
gcc -DHAVE_CONFIG_H -I. -I. -I../../src     -g -O2 -c disp.c
disp.c:39: getopt.h: No such file or directory

I was able to build it successfully by hand:
gcc -DHAVE_CONFIG_H -I/usr/local/include -I. -I../../src     -g -O2 -c disp.c
gcc  -g -O2  -o disp  disp.o -L/usr/local/lib -lncurses -lgnugetopt 

After this, the curses stuff in disp seems to work just fine on this platform. 
Very cool.
