Upon installing gnome3, I was unable to get the Applications Menu in Gnome Tweak Tool. It transpired that gnome3 package was missing gnome-menus. Installing the gnome-menus package separately fixed the problem and I was able to the Applications Menu.
Is this still relevant?
Appears to be so. I don't see gnome-menus listed in RUN_DEPENDS
in the latest x11/gnome/Makefile.
