This seems related to the changes introduced from `ppx_tools_versioned.5.2` to `ppx_tools_versioned.5.2.1` (see https://github.com/mirage/ocaml-cstruct/pull/204 for more info on why there is now a need for explicitly stating runtime dependencies on `ppx_tools_versions`).

Ok thanks that's a way. However note that with the dune trailer added as you suggested along with a `generators = [… "menhir"]`, the generated `dune` file has multiple rules...

Yes indeed. I'll leave the issue open as a reminder.
