Comment 7 Mats Lidell gentoo-dev 2020-01-12 22:25:11 UTC
Unison v2.51.2 is according to upstream compatible with Ocaml-4.06. Compatibility with later versions of Ocaml has been added to unison since the release of v2.51.2. The latest version in testing we have in the tree is Ocaml-4.09 which thus breaks the unison build.

One possibility is to change the ebuild to set a dependency on ocaml to be "<=dev-lang/ocaml-4.09".
