I use gnome 3 and MATE. How can I some solve this dependency or can add flag "-notification-daemon" or "-nd" to mate-base/mate-1.4.0::mate-overlay, that disable x11-misc/mate-notification-daemon-1.4.0::mate-overlay on is dependency, to install x11-misc/notification-daemon-0.7.6::gentoo (from gnome 2/3)? Reproducible: Always Steps to Reproduce: 1. layman -a mate-overlay 2. emerge =mate-base/mate-1.4.0 3. emerge =gnome-base/gnome-3.4.1 4. Have error, or, if you have not, just emerge -eD --newuse --backtrack=50 --update world (x11-misc/mate-notification-daemon-1.4.0::mate-overlay, ebuild scheduled for merge) pulled in by >=x11-misc/mate-notification-daemon-1.4.0 required by (mate-base/mate-1.4.0::mate-overlay, ebuild scheduled for merge) (x11-misc/notification-daemon-0.7.6::gentoo, ebuild scheduled for merge) pulled in by x11-misc/notification-daemon required by (virtual/notification-daemon-0::gentoo, ebuild scheduled for merge) >=x11-misc/notification-daemon-0.7 required by (gnome-base/gnome-fallback-3.4.1::gentoo, ebuild scheduled for merge)
If I add virtual/notification-daemon::gentoo to /etc/portage/package.mask, I have: (x11-misc/mate-notification-daemon-1.4.0::mate-overlay, ebuild scheduled for merge) pulled in by >=x11-misc/mate-notification-daemon-1.4.0 required by (mate-base/mate-1.4.0::mate-overlay, ebuild scheduled for merge) (x11-misc/notification-daemon-0.7.6::gentoo, ebuild scheduled for merge) pulled in by >=x11-misc/notification-daemon-0.7 required by (gnome-base/gnome-fallback-3.4.1::gentoo, ebuild scheduled for merge) x11-misc/notification-daemon required by (virtual/notification-daemon-0::mate-overlay, ebuild scheduled for merge)
The overlay must be missing virtual/notification-daemon then. Futhermore GNOME is restricted in it's meta packages to the actual notification-daemon. So having the gnome-base/gnome or gnome-base/gnome-light installed won't fly. Nothing to do for Portage anyways, all up to the overlay.
Sorry, will fix the mate metabuild. The issue is that while MATE is friendly enough and can use any of the notification daemons, GNOME's developers have decided to explicitly require notification-daemon. The virtual in the overlay supports any of the 3 being installed, so switching to depend on the virtual instead of mate-notification-daemon.
I change mate-base/mate-1.4.0 ebuild, replacing 52 line to "virtual/notification-daemon". I don't know is it corrent, or not, but now I have to problems.
