OPAM does not init (on FreeBSD)

[PALI Gabor Janos <pgj@xxxxxxx>]

Hi there,

I am trying to use OPAM on FreeBSD/amd64 (10-CURRENT), but I cannot pass
through the "init" phase.  The following happens:

% opam init
New compiler descriptions available:
 -  3.12.1
 -  3.12.1+mirage-unix-direct
 -  3.12.1+mirage-xen
 -  4.00.0+beta2

[28118] ERROR: Package base-unix not found
[28118] ERROR: Package base-bigarray not found
[28118] ERROR: Package base-threads not found
  'opam init' failed


However, it seems all the "missing" packages are there:

% ocamlfind list | grep -E "(unix|threads |bigarray)"
bigarray            (version: [distributed with Ocaml])
threads             (version: [distributed with Ocaml])
unix                (version: [distributed with Ocaml])


Any ideas?
