matplatlib is included as is because it won't work when you include only the bits that are referenced in the "import" graph, I'll check how hard it will be to exclude the tests in this copy.

The only editra I could find was <http://editra.org/> which is an editor, I don't know why that gets copied into your application. How did you install Editra, did you use the binary DMG on the website, or did you install from source?

I don't know what "Locales" is at all. Is there a python package on  your system that is named "Locales"?

That this didn't work for matplotlib is expected, a py2app recipe for matplotlib overrides your exclude option.

The codecs are the stdlib support for translating between bytestrings and unicode in various encodings.  These are implicitly imported when you use the codecs module (either directory or through somestring.decoe("encoding").  Py2app cannot detect if you do this and therefore conservatively includes all encodings just in case they are needed.  Adding a way to specify which encodings should be included would be nice, I'm not sure when I'll get around to implementing this.

Can you reproduce this using a smaller example?  

BTW. Are you trying to package this OpenStereo: http://www.igc.usp.br/index.php?id=openstereo. If so, I can try to reproduce the issue on my machine.
