(I might misinterpret your question, but..)
It just happens that I compiled scsh on Solaris first, where static linking
scsh.image worked, but the resulting heap image couldn't interpret my
scripts in the byte-compilation phase.
Then I tried to compile scsh on Linux, where I couldn't even static-link
scsh.image. I described my two problems in chronological order, but to me,
they are unrelated.

(Just in case..) I remember I had to use this #! line:
#!/usr/local/lib/scsh/scsh.vm \
-o /usr/local/lib/scsh/scsh.vm -- <other options>
!#
The -o /usr/local/lib/scsh/scsh.vm was mandatory under Solaris only (on
other systems it worked, and a little faster, without it).

My machine/sysdep.h is empty :-(.

So I'm not alone.
The manual says:
`In spite of .. we are providing the static linker .. so that people may
get some experience with it.'
Then my experience is that it worked better in scsh 5.0.1.
Any reaction from the scsh maintainers ? (even to say I'll have to wait :-)
Bruno.
