It’s not unusual for some GUI libraries to support multiple backends. It’s a bit weird that this requires propagation, but according to the comment that’s because of the pkg-config files. libxfce4ui-1.pc needs propagation of gtk+@2, libxfce4ui-2.pc needs propagation of gtk+@3. Maybe we could split that package up, so that the different variants are provided by separate variants. Or we could simply not propagate gtk+@2 and only add it to packages that actually use gtk+@2. I’m giving this a try right now. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
