Weird, dh should already take care of this:

$ grep shebang -C1 /usr/share/perl5/Debian/Debhelper/Buildsystem/python_distutils.pm
          # We need to to run setup.py with the default python first
          # as distutils/setuptools modifies the shebang lines of scripts.
          # This ensures that #!/usr/bin/python is used and not pythonX.Y

And, when I rebuild zhone from source, /usr/bin/zhone indeed ends up 
with the proper #!/usr/bin/python shebang.
