Is matplotlib installed? This message is printed when

${PYTHON_EXECUTABLE} -c "import matplotlib"

fails (as in exits with non-zero return code). If you run this on the
command-line using the same python interpreter as VTK, what is the
exit code?

If matplotlib isn't installed, the test should definitely fail --
several elements of that test's output depend on matplotlib's presence
to get correctly renderered.
