geneweb 5.01 has been released, current version in the tree doesnt build with ocaml 3.10. This release does but needs dev-ml/camlp5. I'll attach a diff to the ebuild that should also add optional support for ocamlopt, as it is planned to make it optionnal soon per bug #203886 to ease porting ocaml to architectures that do not have or have a broken native code compiler for ocaml.
