This. For now, we need to prefer qt4, if there is a choice between qt4 and qt5. (Unless upstream has already abandoned the qt4 option, which makes it less of a choice, I guess.) But please set useflags for both options, so the choice is clear to the user. As soon as qt5 goes stable, I think we should switch to qt5 as default where possible. And especially when we have an at-least-one-of or an either-or required-use, we need to have one of the options set as default. -- Cheers, Ben | yngwin Gentoo developer
