[Paraview] Extending Broken in 2.6.0

[Kent Eschenberg]

Extending PV at compile time seems to be broken in 2.6.0. The following 
(slightly edited) is printed when the new filter, vtkCloud, is instanced:

======
# Error or warning: There was a VTK Error in file: 
<src>/Servers/Common/vtkProcessModule.cxx (966)
  vtkProcessModule (0xc448130): Object type: vtkCloud, could not find requested 
method: "SetInput"
or the method was called with incorrect arguments.
while processing
Message 0 = Invoke
   Argument 0 = id_value {811}
   Argument 1 = string_value {SetInput}
   Argument 2 = id_value {589}
ErrorMessage end
ErrorMessage
# Error or warning: There was a VTK Error in file: 
<src>/Servers/Common/vtkProcessModule.cxx (968)
======

This filter was added to 2.4.4 with no problem. I don't see any changes for 
2.6.0 at

Has anyone else been able to extend 2.6.0 at compile time?

Thanks!
