Remmina has support for the SPICE protocol but currently it's enabled/disabled automagically depending on whether spice-gtk is installed or not. I've been maintaining remmina in an overlay for some time and this is one of the changes I noticed your new ebuild needs, I may have a few more later. I believe we need to: 1. add spice to IUSE 2. add "spice? ( >=net-misc/spice-gtk-0.31[gtk3] )" to RDEPEND 3. add "-DWITH_SPICE=$(usex spice)" to mycmakeargs Thanks!
pushed, but I have comments about removing the old ebuilds, 1) request new stable version before remove old stable ones 2) any reason why remove the live ebuild (-9999), not update it? (please open a new bug/PR for removing the old if you still want to..) thanks for your contribution! https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=081a6b99489c18cbb1f0b3097750c2450853b99e
