Recently some team members of the Qt project have adopted these ebuild policies: https://wiki.gentoo.org/wiki/Project:Qt/Policies
I have an issue with the policy adopted under "Requires one of two Qt versions". In my opinion, in the case where a package offers a choice between qt4 or qt5, we should express this in explicit useflags and a REQUIRED_USE="^^ ( qt4 qt5 )". This offers the user the clearest choice. Other developers state that users are not interested in such implementation details, or that forced choice through REQUIRED_USE is too much of a hassle. This results in current ebuilds such as quassel to not make it clear that qt4 is an option. This goes against the principle of least surprise, as well as against QA recommendations. I would like to hear specifically from QA about how we should proceed, but comments from the wider developer community are also welcome. -- Cheers, Ben | yngwin Gentoo developer
