thanks for the infor.

I went back and loaded all the devel rpms that I could find dealing
with jpeg and freetype. Here is what I get now:

PIL 1.1.5 BUILD SUMMARY
--------------------------------------------------------------------
version       1.1.5
platform      linux2 2.4.2 (#5, Aug  1 2006, 17:25:34)
              [GCC 3.3.5 20050117 (prerelease) (SUSE Linux)]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
--- FREETYPE2 support ok
--------------------------------------------------------------------
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.

So, PIL is finding what it needs in the setup script. However, running
the test gives me :

python selftest.py
*****************************************************************
Failure in example: _info(Image.open("Images/lena.jpg"))
from line #24 of selftest.testimage
Exception raised:
Traceback (most recent call last):
  File "./doctest.py", line 499, in _run_examples_inner
    exec compile(source, "<string>", "single") in globs
  File "<string>", line 1, in ?
  File "./selftest.py", line 21, in _info
    im.load()
  File "PIL/ImageFile.py", line 180, in load
    d = Image._getdecoder(self.mode, d, a, self.decoderconfig)
  File "PIL/Image.py", line 328, in _getdecoder
    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available
1 items had failures:
   1 of  55 in selftest.testimage
***Test Failed*** 1 failures.
*** 1 tests of 55 failed.

is it that 'lena.jpg' is not found, ir is a decoder elsewhere not
found?
