If the compiler is upgraded, but libraries are not recompiled, then the whole compilation fails with a slightly obscure error like:

I was wondering how to encode the depends_lib so that the OCaml libraries in MacPorts depend on the *exact* version of OCaml they were compiled with, and a subsequent upgrade of the OCaml port will also trigger a recompile of the dependent libraries. Could someone advise me of the TCL-foo to make this possible (if so) ?
There is no syntax in MacPorts to make that possible.
So, you'll have to manually increase the revision of the ocaml ports when the compiler version increases.
