Building lablgtk fails with the error: ocamlfind: sourceView2Enums.ml: No such file or directory

On Fedora 38 x86_64 with opam's default switch having ocaml-4.14.1 I issue the following command:

opam install lablgtk

and get the following output:

The following actions will be performed:
  ∗ install lablgtk 2.18.13
