I built a deb on Debian/sid, which may or may not work on Ubuntu. I was able to upgrade from 3.2.1 on a test box (I haven't installed on my production backup box). Once I installed it, I had to change the my $useFHS from 0 to 1. After that, it seemed to work on a subset of boxes on my network.
I'm attaching the deb I built, feel free to test it out, with the standard disclaimers. :)
