dev-ml/opam-2.0.6 - inconsistent assumptions over implementation Graph

[XVilka]

Same problem with dose/ocamlgraph - maybe it should be handled in the ebuild somehow (not sure it's possible) instead of manually rebuilding the dose all the time.

dose has >=dev-ml/ocamlgraph-1.8.6:= dep which is supposed to handle this automatically ocamlgraph (graph.cmxa) should have no dep besides ocaml, so we can rule out transitive deps

therefore I'll need you to figure out what has changed on your system that has caused this
