OCaml support broken

[cuihtlauac]

Using:

• ocaml 5.1.1
• ocaml-compiler-libs v0.12.4
• ocamlfind 1.9.6

Here is what I do (in a fresh clone, using Ubuntu 23.10):

$ cd languages/ocaml
$ ocaml repl.ml -e "let foo = 1;;"
File "./repl.ml", line 111, characters 23-36:
111 |       use_silently ppf explicit_name
                             ^^^^^^^^^^^^^
Error: This expression has type string but an expression was expected of type
