+  * pck-update - Silvan Calarco:
+    Try to avoid reporting package requirements set with 'Requires:' as build
+    requirements. Unless not better identified requirements are in 'a(b)' form
+    don't report them as build requirements to avoid breaking stage1 builds and
+    causing unneeded circular dependencies.
