Have you tried just building the 4.0.3 package from experimental, without any additional changes? Does that work?

The ldb error in particular seems odd - do you have libldb1 and the other build dependencies installed?

It is normal that there are some errors from dpkg-shlibdeps, it doesn't deal with internal libraries found using rpath very well.

As I understand it, --bundled-libraries incorporates libraries into the package itself so that the package need not rely on system libraries. This seemed like a safe way to ensure that (even if for however unlikely) once the package built successfully, it would *always* be functional. 
There should be no need to use --bundled-libraries. Debian makes sure that the
dependencies for Samba would always be present, while also giving you access to
(security) updates for them. --bundled-libraries also covers only a small
number of the libraries that Samba4 links with.

The reason --bundled-libraries exists is that on some platforms it is a hassle
to manually install all the libraries that Samba uses before actually building
Samba itself. On Debian, this is not necessary since the libraries are already
packaged.

Cheers,

Jelmer
