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.
running build_scripts
$ python selftest.py

------------------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib
To link against installed libraries in a given directory, LIBDIR,
you must use the `-LLIBDIR' flag during linking.
You will also need to do one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

It seems everything is OK ,but it doesn't work!
I run in my own program, the error information is as follows:
Traceback (most recent call last):
File "ImageRecog.py", line 2, in ?
img = Image.open(sys.argv[1]).convert('YCbCr')
File "/usr/lib64/python2.4/site-packages/PIL/Image.py", line 653, in

File "/usr/lib64/python2.4/site-packages/PIL/ImageFile.py", line 223, in
load_prepare
self.im = Image.core.new(self.mode, self.size)
File "/usr/lib64/python2.4/site-packages/PIL/Image.py", line 36, in
__getattr__
raise ImportError("The _imaging C module is not installed")
ImportError: The _imaging C module is not installed
and it's true that the _imaging model not exists!
Can you help me?
thanks!
