1) I modified all the vtk classes that inherit from 

      vtkRectilinearGridToPolyDataFilter
      vtkStructuredGridToPolyDataFilter
      vtkUnstructuredGridToPolyDataFilter

   to

      vtkPolyDataAlgorithm

   since those classes are deprecated and aren't in VTK6.

2) I updated the rzzeus config site file to use Silo 4.9-pre1.
