That file lives in: lib/python2.7/config/config.c.in

On this system Python (and all software) is installed on a high 
performance file system that is mounted read only on the compute system. 
We have to set certain environment vars to get Python to run from this 
location, but PV's cmake code overwrites at least one of them.

I made the following change

diff --git a/ThirdParty/FreezePython/vtkFreezePython.cmake 
b/ThirdParty/FreezePython/vtkFreezePython.cmake
index a94a5d7..405f87b 100644
--- a/ThirdParty/FreezePython/vtkFreezePython.cmake

  execute_process(
      COMMAND ${PYTHON_EXECUTABLE}

lines 1-13/13 (END)

the change got me further but still there are some issues
