[Distutils] MANIFEST.in properly defined but something wrong in setup.py

Dear Distutils-sig members, I'm having some trouble packaging a python project. I have read several guides but I still seem to do something wrong. Could somebody take a look to see what I am doing wrong? Packaging details project:http://stackoverflow.com/questions/13307408/python-packaging-data-files-are-... I think the content of my MANIFEST.in is correct and I am probably doing something wrong in my setup.py file. You can find a list in that link of the configurations of setup.py I have already tried but lead to no success. Best regards
