Installation issue on macOS M1+Sonoma

[correnson]

On my recently upgraded macOS M1 + Sonoma + Up-to-date Homebrew, Lablgtk3 no more compiles :thinking: Here is the reported error:

Hi, I have got the same kind of issue while installing the Coq Platform on macOS M1 + Sonoma + up-to-date MacPorts. The details look different though.

[ERROR] The compilation of lablgtk3.3.1.4 failed at "dune build -p lablgtk3 -j 4".

Those are duplicates of #178 . There is already a fix, waiting for it being merged into opam. https://github.com/ocaml/opam-repository/pull/25574
