I head read that,  but I don't see how that could be the problem.  The 
offending line of my code is:

   vtkPointSet *point_set = vtkPointSet::New();

The version of vtk I'm using is 4.4.2,  and I noticed that vtkPointSet has no 
New() member function,  unless I misunderstand  the macros used in the 
headers;  could the problem be that New() is being inappropriately inherited 
from the superclass?
