libxfce4ui propagates both gtk+@3 and gtk+@2. There is no conflict between these two versions of gtk, because they are installed into separate sub-directories under $prefix/lib. How should we handle exceptions like this? Should packages get a new property that would allow them to specify that they do not conflict with a certain variant? -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
