Would be interesting to have this XMPP client available in Gentoo, since it appears to support a lot of modern XEPs, that other clients (e.g. Pidgin, Telepathy) are lacking. DESCRIPTION="Modern Jabber/XMPP Client using GTK+/Vala" HOMEPAGE="https://github.com/dino/dino" LICENSE="GPL-3"
Looks like this is available in an overlay: https://github.com/csmk/frabjous/tree/master/net-im/dino
Implemented and committed b0b38821930a1a2c2b31f105af5a17f51f213d93, while on XMPP Sprint at Cambridge.
