Py_ssize_t is a type defined by the python C API, but it looks like it
wasn't introduced until Python 2.5, so I'm guess that you have an
older version of python installed? What is the output of "python
--version"?

The matplotlib library requires python >= 2.6, so if your python is
older than this, you'll need to update your python installation, or
disable matplotlib in the ParaView build by editing
CMake/VTKModules.cmake and commenting out this section (around line
350):

# Enable vtkRenderingMatplotlib for math text rendering if python is available
if (PARAVIEW_ENABLE_PYTHON)
  list (APPEND _vtk_modules vtkRenderingMatplotlib)
endif()

I'll push a patch to only enable the matplotlib module when python is
an appropriate version.

Thanks for the report!
