@kde-plasma-5.5 failed to build because of missing some packages kde-plasma/plasma-workspace-5.5.1.1 really requires kde-base/kdelibs-4.14.13-r1 (or fails to compile shell/shellcorona.cpp in line 1052 (appletCreated is missing) kde-plasma/kde-cli-tools fails to build without version 5.17.0 of following: kde-frameworks/kcmutils kde-frameworks/kdesu kde-frameworks/kinit kde-frameworks/kio kde-frameworks/kwindowsystem Finally, kde-apps/kio-extras requires media-gfx/exiv2-0.25-r1 and kde-apps/libkexiv2-15.08.3
Please attach build logs. kde-plasma/plasma-workspace cannot possibly require kdelibs. kde-plasma/kde-cli-tools already depends on those frameworks and the highest version requirement I can find is 5.16.0. kde-apps/kio-extras built OK for me with earlier versions of exiv2.
