[Cuis] Display Driver Missing (not)

[Dan Norton]

I'm trying to move off Doze7 to Debian Linux (jessie). Things were going 
great with Cuis until this noob used dpkg to remove some "unneeded" lib* 
files. In one command entry 100 or so were removed and after that:

d at debian:~/cuis$ cogspur/cogspurlinux/squeak Cuis-Smalltalk-Dev/an.image
produced:

could not find display driver vm-display-X11; either:
   - check that 
/home/d/cuis/cogspur/cogspurlinux/lib/squeak/5.0-3397//vm-display-X11.so 
exists, or
   - use the '-plugins <path>' option to tell me where it is, or
   - remove DISPLAY from your environment.
Aborted

This did not occur prior to removal with dpkg and the file 
"vm-display-X11" is exactly where it's always been, so I think Spur 
needed one or more of those lib* files I deleted. BTW, GNOME, email, 
browser, gedit seem unaffected.

Any help in identifying what Spur needs to find that driver would be 
much appreciated.
