I am trying to build parsexp-0.14.1 with caml-4.12 and it fails to find base.caml:
File "src/dune", line 1, characters 66-75: 1 | (library (name parsexp) (public_name parsexp) (libraries sexplib0 base.caml) ^^^^^^^^^ Error: Library "base.caml" not found. Hint: try: dune external-lib-deps --missing @@default
opam doesn’t find base.caml. Based on its name it should be provides by ocaml itself (?) Where is this package defined?
