[ocaml-platform] OPAM Install of ctypes-foreign fails silently

I'm try to install the package ctypes-foreign using OPAM. It looks like
it works, but actually nothing gets installed.

This is the command I used:

$ opam install ctypes ctypes-foreign
The following actions will be performed:
  ∗  install ctypes-foreign 0.4.0
  ∗  install ctypes         0.4.1
===== ∗  2 =====

=-=- Gathering sources
[ctypes] Archive in cache

=-=- Processing actions
∗  installed ctypes-foreign.0.4.0
∗  installed ctypes.0.4.1

It looks like "ctypes" worked:

$ ocamlfind query ctypes

But ctypes-foreign wasn't installed:

$ ocamlfind query ctypes-foreign
ocamlfind: Package `ctypes-foreign' not found

I can see a directory /home/robert/.opam/system/lib/ctypes-foreign is
created, but it's empty.

I'm new to OPAM, so not sure how to begin debugging this. Any hints much

Many thanks,
