+                    A runtime dependency exists between the two specified
+                    packages, but there is nothing explicit within the recipe
+                    to enable the OpenEmbedded build system to ensure that
+                    dependency is satisfied.
+                    This condition is usually triggered by an
+                    <link linkend='var-RDEPENDS'><filename>RDEPENDS</filename></link>
+                    value being added at the packaging stage rather than up
+                    front, which is usually automatic based on the contents of
+                    the package.
+                    In most cases, you should change the recipe to add an
+                    explicit <filename>RDEPENDS</filename> for the dependency.
