I see numerous packages having: || ( dev-ml/camlp4:= <dev-lang/ocaml-4.02.0 ) Using := inside || () is forbidden and broken. Do I understand correctly that old versions of ocaml do not require additional camlp4, however with newer it is required? If that is the case, then I would sugest adding camlp4-0 that would just pull in <ocaml-4.02.0, and leaving only 'dev-ml/camlp4:=' dep. This includes at least: app-misc/wyrd dev-ml/camomile dev-ml/comparelib dev-ml/deriving-ocsigen dev-ml/enumerate dev-ml/extlib dev-ml/faillib dev-ml/fieldslib dev-ml/lablgl dev-ml/lablgtk dev-ml/lwt dev-ml/macaque dev-ml/ocaml-data-notation dev-ml/ocaml-gettext dev-ml/ocamldsort dev-ml/ocamlnet dev-ml/optcomp dev-ml/pa_bench dev-ml/pipebang dev-ml/pomap dev-ml/pxp dev-ml/typehashlib dev-ml/utop

and reverted, see commit log and e.g. bug #586328 for a proper fix (I don't have time to fix tens of packages atm and don't think there is suddenly any rush about it)
i believe everything that can be fixed in a generic manner has been fixed some remains, please file bugs for individual packages so that proper action can be taken on a per package basis
