I tried to build these vms and the 32-bit vm blew up on me with this:

Here's my attempt to build and run the 4.6 32-bit interpreter on a 
64-bit image, which I had build as above.

rabbit at rabbithole:~/warren/interpreter-4.6/build$ build/squeakvm 
TrunkImage-64.image
could not find display driver vm-display-X11; either:
   - check that /usr/local/lib/squeak/4.14.2-3479/vm-display-X11.so 
exists, or
   - use the '-plugins <path>' option to tell me where it is, or
   - remove DISPLAY from your environment.
Aborted (core dumped)

I cleared DISPLAY and ran again:

rabbit at rabbithole:~/warren/interpreter-4.6/build$ build/squeakvm 
TrunkImage-64.image
squeak: could not find any display driver
Aborted (core dumped)

Not sure what's happening.

I would like to build and run a 64-bit Spur image on a 32-bit non-Cog 
VM. Is building spurstack64src the way to go forward with that?

Yes, I am starting to get it clear. These instructions are for the 4.6 
vm/image context interpreter vm. Please see above.
