[Image-SIG] PIL Installation Issue

[Joe Blubaugh]

I am attempting to install PIL on Ubuntu 7.10.  On running the in-place 
install, I get this output:

    joe at Norrell:/usr/lib/python2.5/Imaging-1.1.6$ python setup.py
    build_ext -i

    To check the build, run the selftest.py script.


Which appears ok (including jpeg support). However, on running the 
selftest.py script, I error on one of the tests:

    *****************************************************************
    Failure in example: _info(Image.open("Images/lena.jpg"))
    from line #24 of selftest.testimage
    Exception raised:

      File "PIL/Image.py", line 375, in _getdecoder
        raise IOError("decoder %s not available" % decoder_name)
    IOError: decoder jpeg not available
    1 items had failures:
       1 of  57 in selftest.testimage
    ***Test Failed*** 1 failures.
    *** 1 tests of 57 failed.

I haven't been able to find a reason for this failure yet. Have you seen 
these kind of install issues before?
