Problem is in ensuring that all binary packages indeed work properly 
with an alien system.

My concrete use case is using recent Compass on an otherwise stable 
Debian.  For my stable systems I require all backported packages to 
actually be built on a stable Debian build environment, so that e.g. 
regression tests are applied for same environment as will be used in

Ideally a packaging helper use few dependencies so as to not require 
last possibl other packages to be packaged without that help.
