+	  JSON-C is now the only supported library for enabling JSON
+	  support for BIND statistics. The <command>configure</command>
+	  option has been renamed from <command>--with-libjson</command>

+	  <command>PKG_CONFIG_PATH</command> to specify a custom path to

+	  <command>configure</command> option does not take the library
+	  installation path as an optional argument.
