Backporting a package from unstable to stable

[Andrew Pollock <debian-lists@andrew.net.au>]

Hi,

To use an example, I'd like to take the source package for Snort (2.0.0-2) 
in unstable and rebuild it against stable so that I can update my 
otherwise stable installation with a newer version of Snort, without 
dragging in all the other dependencies from unstable that just installing 
the Snort 2.0.0-2 binary package from unstable would do.

Is it as simple as using something like pbuilder and tweaking the 
Build-Depends to match the versions of the packages that are in stable?
