I thought that it was a task of upstream what of listing all right dependencies

Every 'import' statements indicate a python module (I think) so for example
(related package names enclosed in parenthesis):

distutils (python-distutils-extra) - cmd.py (pypy-libs, python-libs)
                                        - os.py (python-libs)
                                        - glob.py (python-libs)
                                        - shlex.py (python-libs)
                                        - subprocess.py (python-libs)
                                        - shutil.py (python-libs)
                                        - polib.py (python-polib)
                                        - ConfigParser.py (python-libs)
                                        - codecs.py (python-libs)  
                                        - msgfmt -->

msgfmt.py -- sys.py (shedskin)
          - os.py (python-libs)
          - getopt (shedskin)
          - struct (shedskin, python-libs)
          - array (shedskin)

comun.py  -- os.py (python-libs)
          - locale.py (pypy-libs, python-libs)
          - gettext.py (python-libs)


and so on.
However, if it is a right procedure, the same '.py' file is provided as a part
of more rpm packages and it is difficult to know which is the right one.

Maybe they are useless.
