Hi Rich,

In Makefile.am files, installation-related rules
must honor the $(prefix) Makefile variable.  For example,
in many Makefiles you'll find files being installed to
$(DESTDIR)$(bindir), with these definitions:

    bindir = ${exec_prefix}/bin
    exec_prefix = ${prefix}

Currently, $(OCAMLLIB) (set from m4/ocaml.m4 by running $OCAMLC) is set
to /usr/lib64/ocaml for me.  If we could make it include $(exec_prefix),
that would solve this problem.
