portgroup ocaml: cannot build with topkg?

[pguyot (Paul Guyot)]

I am very confused by the topkg build of ocaml portgroup. It works fine locally (macOS 14) but fails on the CI under both macOS 11 and macOS 13.

This error is very weird and blocks two new ports of mine but it can also be observed in other PRs.
