Oops, after 3 years I just noticed that the link I sent in the previous email was wrong (to the repository I put on github in the hopes of being helpful despite the lack of Debian Official uptake). The correct one is (a gbp repo):
https://github.com/rowanthorpe/sflowtool-debian Anyway, that is still based on a very old upstream version, but because the packaging framework is in place it would be relatively easy to sync it with the latest upstream version, if anyone ever indicates they would find it useful.
