Hi there,
I am trying to install PIL 1.1.5 with jpeg decoder.
I installed from RPM and also from sources the libjpeg-6b into 
I change the ROOT_JPEG in setup.py to point to that location.
When I install PIL 1.1.5, I get a message that the JPEG support is OK. 
But when I test it, I get a message of decoder error. Someone could help 
me? I tried by myself in python and received the same IOError message.

version       1.1.5
platform      linux2 2.3.5 (#1, Nov 15 2005, 16:30:27)
              [GCC 4.0.0 20050519 (Red Hat 4.0.0-8)]
*** TKINTER support not available
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
*** FREETYPE2 support not available
To add a missing option, make sure you have the required
library, and set the corresponding ROOT variable in the
setup.py script.
To check the build, run the selftest.py script.
