Removing that option did the trick, however the vm does not run. I
suspect it is something trivial. I tested in place, without make
install. With my build directory (work) the current directory I enter
the command

$ ./squeak /home/gary/Squeak4.2-10966.image

and get this undefined symbol error:

/usr/home/gary/OpenSlate/Squeak/Squeak-4.4.7.2357-src/work/vm-display-X11/so.vm-display-X11:
Undefined symbol "error"
could not find display driver vm-display-X11; either:
  - check that /usr/local/lib/squeak/4.4.7-2357/vm-display-X11.so exists, or
  - use the '-plugins <path>' option to tell me where it is, or
  - remove DISPLAY from your environment.
Abort trap (core dumped)

Note that "check that
/usr/local/lib/squeak/4.4.7-2357/vm-display-X11.so exists" is false.
It should be looking for
/usr/home/gary/OpenSlate/Squeak/Squeak-4.4.7.2357-src/work/vm-display-X11/so.vm-display-X1l.
Do I need to modify the squeak shell script, or just run make install?
