when trying to update my system, i get the following, as kdelibs no longer has the aqua use flag.

emerge: there are no ebuilds built with USE flags to satisfy ">=kde-frameworks/kdelibs-4.14.22:4[-aqua]".
!!! One of the following packages is required to complete your request:

• kde-frameworks/kdelibs-4.14.36::kde-kit (Missing IUSE: aqua)
• kde-frameworks/kdelibs-4.14.34::kde-kit (Missing IUSE: aqua)
  (dependency required by "kde-apps/libkdegames-4.14.3-r1::gentoo" [installed])
  (dependency required by "kde-apps/kolf-17.08.1::kde-kit" [ebuild])
  (dependency required by "kde-apps/kdegames-meta-17.08.1::kde-kit[qt4]" [ebuild])

  (dependency required by "kde-apps/kde-meta-17.08.1::kde-kit" [ebuild])
  (dependency required by "@selected" [set])
  (dependency required by "@world" [argument])

sometimes i get the above, and other times i get the following:

emerge: there are no ebuilds built with USE flags to satisfy ">=kde-frameworks/kdelibs-4.11.22:4[-aqua]".
