Again thanks to Marcello Teodori, now I'm able to automatically create .deb packages on my development MacBook Pro.

Marcello explained me how to install the required application, dpkg - and the procedure works for a lot of typical Linux applications.
  1. install MacPorts;
  2. add to your PATH the directory /opt/local/bin;
  3. execute the following command to update the MacPorts installation:
    sudo port selfupdate
  4. at last install dpkg:
    sudo port install dpkg
Et voil
