It looks like you are trying to run something out of your build directory?
That will not work. The VM needs to be able to find its plugins and
VM modules in known directory paths, and if you accidentally mix up
the executable modules from various VMs, you will get core dumps and
"module not found" problems.

Try "sudo make install" to get a proper installation, then "squeak myimage".
The /usr/local/bin/squeak script will look at your image, figure out what
executables to use, and run them from the appropriate
/usr/local/lib/squeak/<someversion>/ directory.

Note that both Cog and Spur VMs may attempt install on top of the same
/usr/local/bin/squeak and/or /usr/bin/squeak path. On my systems, I resolve
the conflicts by renaming the cog and spur VMs to /usr/local/bin/cog and
/usr/local/bin/spur respectively. So if you have spur installed now as
/usr/local/bin/squeak, you may want to rename it to /usr/local/bin/spur
before you do your "sudo make install".
