  # Exactly identical to buildPythonPackage's version but for the
  # `--old-and-unmanagable`, which I removed. This was removed because
  # this is a setuptools specific flag and as zim is overriding 
  # the install step, setuptools could not perform its monkey
  # patching trick for the command. Alternate solutions were to
  #
  #  -  Remove the custom install step (tested as working but
  #	also remove the possibility of performing the xdg-cmd
  #     stuff).
  #  -  Explicitly replace distutils import(s) by their setuptools
  #	equivalent (untested). 
  #
  # Both solutions were judged unsatisfactory as altering the code
  # would be required.
  #
  # Note that a improved solution would be to expose the use of 
  # the `--old-and-unmanagable` flag as an option of passed to the
  # buildPythonPackage function.
  #
  # Also note that I stripped all comments.
