Hello,
Thanks for working on this, and congrats on your first package, which is
not an easy one! :-)
Some preliminary comments:

My understanding (but I’m no expert) is that this is a VM that can run
Pharo bytecode, but it’s not “the” Pharo VM. Is it correct?

Consequently, it looks like this should be called ‘opensmalltalk-vm’,
no?

Or maybe there’s a special command to run them?

Those symlinks look somewhat inelegant to me. :-)
Could we instead arrange so that the VM searches for those files in
their right place? Often that involves substituting things like
“libfoo.so” in the code with the corresponding absolute file name (see
for example how this is done for Racket.)
Last question: does this Git checkout contain binaries, such as
Smalltalk images? IOW, is this being built entirely from source, or is
it bootstrap from opaque binaries? (I know that Pharo itself is or used
to be bootstrap from very old Smalltalk images and that work was ongoing
to get rid of them and have a nicer bootstrapping story.)
Thank you,
Ludo’.
