Hi -
there is a Debian developer which has declared that he will maintain the b.a.t.m.a.n. Debian-package. We are going to release 0.1.1. soon, which is a bugfix release. If we are satisfied with the maturity of the code we'll ask him whether he would like to go ahead and add the package to Debian.
Currently you have to build your own.
