tuareg.3.0.0 fails to load in emacs on macOS when installed using opam #300

I’m an OCaml newbie, so please forgive me if I did something wrong.

Summary

I just tried a fresh install of OCaml and related tools on macOS. I’m using the directions from Real World OCaml. When installing tuareg.3.0.0 via opam, I can’t get tuareg-mode to work in emacs. Everything works fine with tuareg.2.2.0.

Steps to reproduce

  1. Install emacs via homebrew (brew install --cask emacs).
  2. Install opam, etc. 
    brew install opam
opam install core core_bench utop
opam install user-setup tuareg ocamlformat merlin
opam user-setup install
  3. Try to open an existing OCaml file (emacs test.ml)

Expected Results

The file will open and tuareg-mode will be enabled (code will be syntax highlighted, etc.)

Actual Results

The following message is displayed in emacs:

File mode specification error: (file-missing Cannot open load file No such file or directory tuareg-compat)

System Details

MacBook Pro with Apple M1 Max macOS 12.6 emacs 28.2 merlin 4.6-414 ocaml 4.14.0 ocamlformat 0.23.0 opam 2.1.3 tuareg 3.0.0 user-setup 0.7

Additional Notes

Again, if I install tuareg.2.2.0, everything works as expected.

This is fixed in version 3.0.1.
