After long hours of hard work and not enough sleep, I just finished the version of a set of unofficial Biblepay Ubuntu Deb files, available via Launchpad PPA:
https://launchpad.net/~lichtsucher/+archive/ubuntu/biblepay

There is also a wiki page for that:
http://wiki.biblepay.org/Ubuntu_Packages

I hope many users will find them useful

If you want to learn more about how to build these files for your own, please visit my github project for the "Biblepay deb builder":
https://github.com/Lichtsucher/biblepay-deb-builder

There is a proposal for that, too:
