I see.  Not an easy one to solve however.  The OCaml library path
comes from running:

  $OCAMLC -where

This is not an (especially) peculiar OCaml thing.  For example we
detect the Python library path using:

  $PYTHON -c "import distutils.sysconfig; \
              print (distutils.sysconfig.get_python_inc ());"

This allows multiple parallel Python installations to get along on
Debian.  The user just specifies the $PYTHON binary and everything
works off that.  So I'm fairly sure the same bug exists in some
Python, Perl and Ruby code in libguestfs too.
