So, what is wrong with recompiling dpkg against the new library? The old
library is broken, so we have to move, and forward is the only logical
direction.

The first item is not necessary, very difficult, and likely to deliver
its own set of problems.
Item two can't be done if you impliment item 1. Only by installing the new
library will we see which packages need to be recompiled.
If you advocate item 3 the other two are not necessary, and item 2 becomes
automatic.

I have a fixed package ready to go, so lets move forward!

Waiting is,
