[Image-SIG] python install problem 1 test failed selftest.testimage

[Fredrik Lundh]

It tries to tell you that PIL's _imaging.so module was built without
JPEG support, which means that the setup.py script couldn't find or
set up the libjpeg library.

If setup claims that it did find libjpeg, make sure you don't have
multiple _imaging.so modules around (the selftest in 1.1.6 can
sometimes accidentally pick up older versions; the upcoming 1.1.7
version is a bit more careful, but it too could probably provide a bit
more details when this happens).
