It looks like you are writing your code using C++.  If so, then you 
need to add the following line to your program: #include "vtkPolyData.h"

See the thread starting with this message from 
yesterday:  http://public.kitware.com/pipermail/vtkusers/2005-July/081002.html.

Tcl can handle the fact that vtkPolyData is a subclass of vtkDataSet, 
but C++ needs the #include mentioned earlier to get it right.
