We should probably package this but it depends on masked xcb stuff (x11-libs/xcb-util-0.3.5) and I don't want to break my system testing that. http://releases.xfce.org/feeds/project/xfce4-volumed https://launchpad.net/xfce4-volumed
xcb is only masked in soon-to-be-deprecated 2008.0 profiles, use 10.0
