So people with KDE 5 can install winetricks with kde useflag without blocking dependencies. Thank you! Reproducible: Always
OK. Normally, ebuilds in the main portage tree are not allowed to depend on things in an overlay, but an ||-dependency where one of the options is in the main tree should work, since it's guaranteed to be satisfiable without overlays. + 18 Apr 2015; Alexandre Rostovtsev <tetromino@gentoo.org> + winetricks-20150416.ebuild, winetricks-99999999.ebuild: + Depend on kde-base/kdialog || kde-apps/kdialog for kde5 users (bug #547038, + thanks to Julien Papasian).
I got inspired by the similar bug #538638 so this should indeed be OK, thank you!
