!!! Problem resolving dependencies for net-irc/quassel !!! The ebuild selected to satisfy "quassel" has unmet requirements. - net-irc/quassel-0.12.4::gentoo USE="ayatana crypt server ssl -X -dbus -debug -kde -monolithic -phonon -postgres -qt5 -snorenotify -syslog -webkit" ABI_X86="64" The following REQUIRED_USE flag constraints are unsatisfied: ayatana? ( any-of ( X monolithic ) ) What I really miss here is the '-X*' bit that tells me that REQUIRED_USE conflict started happening because USE=X is no longer set.
