[Pythonmac-SIG] Application without py2app?

you made my day :-)

This was exactly the information I was looking for.
After some hours of trial and error I have a perfect working  
environment now.
I used the Bundlebuilder script to set up a working application  
bundle based on a python executable.
Then I decided to drop SPE and installed the latest Eclipse with  
PyDev instead.
The tricky part was to get Eclipse to use the Python executable  
inside the bundle for debugging and launching.
But I found out that this could easily be done with a symlink.
Now I can set a breakpoint anywhere and step through my code with a  
decent IDE.
Very nice.

Thanks a lot for your help.
