I may have spoken too soon regarding this problem being solved.  The issue
now is that foo.cmx is linked *after* the "main" module, main.ml.  I thought
I could influence Ocamlbuild's dependency graph by adding the following
extra after_rule:

dep ["ocaml"; "ocamldep"; "file:main.ml"] ["foo.ml"];

However, this does not seem to work.  Any ideas on how I can convince
Ocamlbuild to link foo.cmx and to do it before main.cmx?

On a related note, if there's one tool in the Ocaml ecosystem that
desperately needs a manual is Ocamlbuild.  I find myself mostly
cargo-culting when I interact with it: the documentation is sparse
and all over the place, making it very difficult to grok how the
whole fits together. /end rant.
