I've checked this already. It was and is executable. But this doesn't matter. A python file is not a binary. And you need always python to start the file: python /usr/bin/panucci

Hmm... I will remove now the git code and install panucci again from the repos. Perhaps I could see a symlink or something like that.

Edit: No symlink as far as I can see. Perhaps something new for me I can't understand so far... (the N900 is my first Linux Device )
