问题
I followed these instructions:
http://proteus-tech.com/blog/cwt/install-pil-in-snow-leopard/
And everything went as described.
However, at the end, I tried running:
python selftest.py
to verify that everything is working properly, but I get:
*** The _imaging C module is not installed
I then run the python interpreter and tried:
import _imaging
and get this error:
Traceback (most recent call last): File "", line 1, in ImportError: dlopen(/Library/Python/2.6/site-packages/PIL/_imaging.so, 2): Symbol not found: _jpeg_resync_to_restart Referenced from: /Library/Python/2.6/site-packages/PIL/_imaging.so Expected in: flat namespace in /Library/Python/2.6/site-packages/PIL/_imaging.so
This is on my first Mac, so apologize if I'm missing anything obvious, but any help you could provide would be greatly appreciated.
Thanks!

The problem happens because jpeglib is not available as part of standard MAC OS X distribution for Leopard and Snow Leopard.
The solution is as follows: - compile lib jpeg - make sure tha libjpeg62.dylib is available on your DYLD_LIBRARY_PATH (you might like to put it in places like /usr/local/lib)
Useful instructions are available here

Ok, got it working thanks to Shailesh's help. First, I ran this:
otool -L /Library/Python/2.6/site-packages/PIL/_imaging.so
to see where the dependencies were. I removed those references to libjpeg, and then recompiled libjpeg and PIL (following the instructions in the link below) and then everything worked.
