After eix-sync I tried emerge -pvDu --with-bdeps=y --changed-use @world and I get circular blocks. Ebuild for gwenview-15.12.1 requires libkipi:5 whereas ebuild for digikam and kipi-plugins require libkipi:4 Although libkipi is slotted, both :4 and :5 can't be installed on the system at the same time: emerge =kde-apps/libkipi-15.12.1 Calculating dependencies... done!

This line is the key: [blocks B ] kde-apps/libkipi:4[-minimal(-)] ("kde-apps/libkipi:4[-minimal(-)]" is blocking kde-apps/libkipi-15.12.1) Set USE=minimal for libkipi:4 and you're set. The plasma profile should pick that up as well, thx for the report.
Thanks, fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=15aff507d695b9ab08855566e20a541ffd2f244b
