Backport building is even easier. For the most part, no source changes are required. All you have to do is use "dch -i" to create a new changelog entry(*) acknowledging that it's a backport, then run pbuilder on this new source package.
The exception is when the Jaunty version requires a new build dependency compared to the Intrepid. You can look at the debian/changelog entries to make an educated guess about whether or not that was necessary. Usually it's just for forcing a build against a newly uploaded library in Jaunty or Debian Sid and safe to remove, but when it's not, I've previously asked Ubuntu devs to make it very clear in the changelog that they weren't kidding when specifying a build dependency version (for example, nasty bugs in supporting libraries) (*) The new changelog entry should be a LOWER version number than Jaunty; this is so that when you upgrade, you are guaranteed to pull in the new Jaunty version. If your backport had the exact same or higher version number as the Jaunty package then APT may not consider it as needing to be upgraded, leading to confusion and dependency headaches in your next upgrade! The "~" operator in the version is very helpful: 1.2.3-1~foo is less than 1.2.3-1. So, Ubuntu convention is to append "~intrepid1" to the first attempted backport, "~intrepid2" to the 2nd, and so on. Various unofficial packages uses other ~suffixes so feel free to pick one that identifies your backports uniquely! P.S. Also see the "prevu" tool in the Ubuntu repos: https://wiki.ubuntu.com/Prevu It's designed to automate this process in one fell swoop, such as "prevu bash" which goes to LaunchPad and automatically grabs the newest Jaunty sources for bash, and builds it. It is powered by pbuilder -- in fact it uses the "pdebuild" invocation of pbuilder. Prevu also functions just like the "pdebuild" command when you run it with no arguments within a Debian source directory so you can use it as a replacement for your pbuilder setup.
