5. Build the library.  We recommend that you do an in-place build,
    and run the self test before installing.

         $ cd Imaging-1.1.6
         $ python setup.py build_ext -i
         $ python selftest.py

    When the build finishes, a summary report is shown.  Make sure
    that the optional components you need are included.
