[Pythonmac-SIG] PIL and py2app on Leopard

[Martin Dunschen]

The recommendation is to import like this:

import Image
...

not
from PIL import Image
...

This reqires that PYTHONPATH is set up to find the module.


PIL should be in your PYTHONPATH environment variable. Test this:

import sys
print sys.path

and see if PIL is somewhere in there.

When you run setup.py, does it find the module Image? Check the output.
Put some debug code into the script: print the path for example from 
your application.

I take it that if you run your python without wrapping it into an 
application everything works as expected?
