What is modules.scm?
It looks as DUMP-SCSH-PROGRAM doesn't initialize the environment of
the run-time system correctly. As a consequence
INTERACTION-ENVIRONMENT is set to the wrong package. There is no
simple fix but it's on my TODO list.

I think this is difficult considering the way you start scsh. You
would need the -o switch which is not available if you start the VM
