Well, this code excerpt doesn't tell us at all how dpkg is currently used
in britney. Can you point us to the relevant code ?
In the end, I suppose that the right path is to export whatever is needed
in libdpkg and make that library a shared one instead of a statically
linked one. After that you can of course build a python wrapper module.
But you will have to talk to Guillem for more specific details.
