+Subject: [PATCH] libgd: add conflicts to each other
+
+The full variant should conflict with the default variant. This prevents that
+libgd and libgd-full could be installed side by side, and also, the full
+variant should provide the libgd. Otherwise, if you install libgd-full,
+you can not install vnstat.
