* you don't have to patch it, just install it into private directory
and `dh_link /usr/share/yourpackage/script /usr/bin/script`
* dh_python2 will take care or byte-compilation (including rtupdate hook
to handle change of default Python version), all you have to do is to
follow /usr/$share_or_lib/$binary_package_name/ schema for private dir
location or adding path to that dir to dh_python2 call in debian/rules

yeah, pythonX.Y-foo/Python-Depends was a good idea but... well, it was
never used properly and since Python 2.7 is the last Python 2.X version
- we don't have to care about it anymore
