[Paraview] Is There An Error In vtkSocketCommunicator (2.4.2)?

[Clinton Stimpson]

I think it is because the vtkConfigure.h is written out before CMake has 
a chance to go in the Parallel directory to find out whether to use 
socklen_t or int.  A second run of cmake updates the vtkConfigure.h file 
with the right stuff, whereas the CMakeCache.txt file doesn't change at all.
