Ok, It seems I solved the problem. There are some stacks/packages wiki pages (like http://www.ros.org/wiki/motion_planners ) that are referring to svn repository ../branches/ros_lib_fix instead to the usual /trunk. After replace the code from /trunk, it compiles fine. Just one question: is it a documentation/link error, or where is a particular reason?
