Strange thing is I downloaded the mac package from pythonmac but the  
installer says there is no python 2.5 on my system???
I'm using Leopard with Developer Tools so it is there for sure.

I installed PIL from source calling setup.py, I have the package in  
site-packages but no PIL.pth.
after adding PIL.pth I can use Import Image.
1 step forward :-)

yepp it is there

After fixing the PIL.pth i could generate one app where i could see  
the site-packages like PIL inside the app-package but just one time.
Now I don't even get an error the app is just crashing on startup.

i will look into it tomorrow an try to build up everything step by step.
Is there a log or something automatically written with the python  
errors of the app? If not how can I achieve this?

Thanks a lot so far I hope I will manage to get it running and report  
how it is going.
