You are missing all of the specific vtkPolyData member functions.

With VTK 5.2 I am getting:

['AddCellReference', 'AddReferenceToCell', 'Allocate', 'BuildCells',
'BuildLinks', 'ComputeBounds', 'CopyCells', 'CopyStructure',
'DeepCopy', 'DeleteCell', 'DeleteCells', 'DeleteLinks', 'DeletePoint',
'GetActualMemorySize', 'GetCell', 'GetCellBounds',
'GetCellEdgeNeighbors', 'GetCellNeighbors', 'GetCellPoints',
'GetCellType', 'GetClassName', 'GetDataObjectType', 'GetGhostLevel',
'GetLines', 'GetMaxCellSize', 'GetNumberOfCells', 'GetNumberOfLines',
'GetNumberOfPieces', 'GetNumberOfPolys', 'GetNumberOfStrips',
'GetNumberOfVerts', 'GetPiece', 'GetPointCells', 'GetPolys',
'GetStrips', 'GetUpdateExtent', 'GetVerts', 'Initialize',
'InsertNextCell', 'InsertNextLinkedPoint', 'IsA', 'IsEdge',
'IsPointUsedByCell', 'IsTriangle', 'NewInstance',
'RemoveCellReference', 'RemoveDeletedCells', 'RemoveGhostCells',
'RemoveReferenceToCell', 'ReplaceCellPoint', 'Reset',
'ResizeCellList', 'ReverseCell', 'SafeDownCast', 'SetLines',
'SetPolys', 'SetStrips', 'SetVerts', 'ShallowCopy', 'Squeeze']

I would think this is an issue with your MacPort package. Either raise
the question in there forums or try to rebuild VTK from scratch on
your system (if you have cmake on your system it should be easy).
