As I mentioned earlier in this bug, the main problem isn't convincing
us why they are needed, it's the lack of any patches to address this
shortcoming in sbuild.  More than anything else, we need someone to do
the work to implement resolving of alternative build deps.

If you have the time to look into it, a patch implementing alternative
build-dep installation would be very much appreciated.

The current sbuild code now has the ability to select alternative
build dependency algorithms (so as to no affect backward compatibility
and allow such experimentation), so it should be reasonably
straightfoward to add an additional algorithm.


Thanks,
Roger
