Debian ships a default C++ compiler which is the same that was used to
build the provided libraries, except during transitions (and stable
users don't see those transitions).
Users building applications with another compiler should really know
what they are doing.

Why can't people understand that linking to a static library is BAD ?

Using a strict policy can almost guarantee this. Why do you think people
have been thinking for months about a suitable transition plan for G++
3.2 ? You are not alone in the world, and hundreds of other C++ software
have exactly the same issues. Why do you think appropriate solutions for
these programs are not suitable for yours ?

Such specious arguments will never justify an exception for ardour.

What we are speaking of here is building a Debian package, with a
maintainer. Users don't build the package, the maintainer and the
autobuilders do. The maintainer ensures that the package is built with
the compiler that was already used to build the libraries it depends on.
All of this guarantees the program will work, and with *dynamic*
libraries, while the user never has to build the software. If the user
doesn't build the software himself, all the issues you describe will
never appear.
