It seems you forecfully prevented installation of Recommends. I'm not using pondus myself and do not know whether it should rather be in the list of Depends but the former maintainer Eike Nicklas (who is also upstream) has most probably considered this the right dependency. I'd say if you prevent installation of Recommends you need to deal with this kind of things on your own and its not really a bug inside the package, isn't it? Kind regards Andreas.
