devel/ocaml-findlib errors

[Sad Clouds <cryintothebluesky%googlemail.com@localhost>]

Hi, trying to build sysutils/xentools41, which depends on
evel/ocaml-findlib, and this package is giving me errors about missing
files:

.... loads of these

pkg_create: can't stat
`/opt/pkg.obj/devel/ocaml-findlib/work.atom/.destdir/opt/pkg/lib/ocaml/site-lib/unix/META'
pkg_create: can't stat
`/opt/pkg.obj/devel/ocaml-findlib/work.atom/.destdir/opt/pkg/lib/ocaml/topfind'
pkg_create: lstat failed for file lib/ocaml/site-lib/bigarray/META: Not
a directory *** Error code 2

Stop.
make: stopped in /opt/pkgsrc/devel/ocaml-findlib
*** Error code 1

Any ideas?
