I fired up the VM and, in the terminal, ran
objdump -p polyml/bin/poly
and I see the output contains:
Dynamic Section:
...
RPATH /root/polyml/lib
...
If that RPATH were correctly set (to /home/guest/polyml/lib) I suspect
you wouldn't need to set LD_LIBRARY_PATH in the environment.

Thanks Phil, I found I needed to set
LD_LIBRARY_PATH as well as PATH to $HOME to use interpreter.
I really appreciate the helpful information from this community!

You can specify any prefix to install to - this does not affect how
dependencies are found. However, depending on your choice of prefix,
you may need to manually add <prefix>/bin to PATH. Depending on your
Linux distribution, it would probably be more idiomatic to do a
per-user
install to
$HOME/.local
to avoid cluttering the home directory. Also, if you have Poly/ML
installed system-wide via the package manager, you would need to make
sure that <prefix>/bin occurs in the path before the system bin
directory, to ensure your user version is found first.
There are some instructions previously posted here:
http://lists.inf.ed.ac.uk/pipermail/polyml/2017-July/002038.html
which also show how to disable the package manager version of
Poly/ML on
Fedora.

I've now changed the ELF exporter to write the data to .data.rel.ro
<http://data.rel.ro>.
The byte code interpreted version (--disable-native-codegeneration) now
builds without a problem on Alpine Linux and on SELinux with hardening
turned on. That isn't a complete solution because it doesn't deal with
native code but it does show that if code could be handled everything
else will work.
I see this primarily as future-proofing Poly/ML. It's not unlikely
that
a future release of, say Mac OS X, might outlaw TEXTRELs.
