The reason for this is the difference between dry packages (those that use rosbuild/rosmake) and wet packages which are based on caktin and use catkin_make for compiling. Rosbuild packages can use wet ones, but they are seen as "external" and this is why you see many ROS_NOBUILD messages.
You can find more information here http://wiki.ros.org/catkin/conceptual_overview and a guide for the migration here http://wiki.ros.org/catkin/migrating_from_rosbuild
