The erlang 23 update broke plenty of packages using rebar, see e.g. #722998. The issue is that rebar uses a no longer supported flag "-lerl_interface". It seems rebar2 is deprecated and replaced with rebar3, but there's currently no maintainer for rebar in Gentoo. CCing erlang maintainers to keep them updated on the situation. (I have no interest in maintaining rebar myself, I "just" want to keep ejabberd working and with the dependencies plenty of these issues have been assigned to the ejabberd team.) The "-lerl_interface" flag can be patched out of rebar and then the packages should all work again. I'm attaching an updated ebuild and patch and will commit them if nobody complains in a few days.

Hanno, Might I ask how (or if) you were able to resolve building dev-erlang/jose (also required by ejabberd) against dev-lang/erlang-23.0?
