[Caml-list] .opam structure question

Greetings, probably the wrong forum for such a naive question but hopefully
someone can answer it in a couple of keystrokes! I am using OCaml makefiles
across slightly skewed versions (4.02.1 and 4.02.3). In my local Makefile,
I'm specifying an explicit path to OCamlMakefile:

~/.opam/4.02.1/lib/ocaml-makefile/OCamlMakefile:

that includes the release version 4.02.1. But I would prefer for this same
Makefile to work on version 4.02.3 too.  It seems really wrong to be
specifying an explicit version number in a path. On my 4.02.1 version, I
was able to replace the version number by "system". This seems to work ---
there is a /lib/ocaml-makefile/ folder there.  But this same hack did not
work on the 4.02.3 system.

So my question is, what is the recommended (i.e., modular and portable) way
to address an OPAM resource such as OCamlMakefile? I suppose I shouldn't
have to know much of anything about the structure of the .opam directory.
(?)

Thanks!
