Quoth the man page: --build-dep-resolver=resolver … The aptitude resolver is very similar, but smarter and slower, and it will consider all alternatives by default; it is suited to more complex situations, such as building packages for the experimental distribution, where packages need installing from multiple suites (unstable and experimental). … --resolve-alternatives Allow the use of alternatives in Build-Depends, Build-Depends-Arch and Build-Depends-Indep. This is the default for the aptitude dependency resolver. so there shouldn't be a need to use --resolve-alternatives with --build-dep-resolver=aptitude. The python-tornado backport didn't even make it to the buildd, so the issue you're seeing is probably related to wanna-build.
