Yes, Kd_tree.clear() is in the manual, but doesn't seem to be implemented. 
I see this problem too.

If I'm not wrong, it might be as simple as adding the following lines to 
kd_tree.h:
//////////////////////
class Kd_tree {
public:
// [..........]
  void
  clear() const
  {
          pts.clear();
          return;
  }
// [..........]
};
//////////////////////
