libperl4caml-ocaml-dev 0.9.5-5build4 (s390x binary) in ubuntu focal

 perl4caml allows you to use Perl code within Objective CAML (OCaml),
 thus neatly side-stepping the old problem with OCaml which was that it
 lacked a comprehensive set of libraries. Well now you can use any part
 of CPAN in your OCaml code.
 .
 This package provides the tools necessary to use perl4caml in your own
 programs. To get the documentation, please install libperl4caml-ocaml-doc.
