No, you understood me wrong.
I build-depend on liblapack-dev, which depends on
  libatlas-base-dev | libblas-dev | libblas-3gf.so
But I want to avoid to build with libatlas-base-dev as libblas-dev is more than
enough in this case (and I need to build-depend on it anyway).
So it should be safe to build-conflict against libatlas-base-dev as all
dependencies are solved - this works well in pbuilder, but sbuild still fails to
solve that.

Hope that explains it better.
