The package depends on libberkeleydb-perl which should be removed with the duke release. Please consider porting this package to a different DB or drop the memory offload feature. I have just noticed that my proposed solution for this was reverted.
I would like to understand why, though? In #987013 I see the maintainer objecting to the removal and I see them making regular uploads of this package as well. Yes, modulo free time. dropping this feature is not going to happen. It caused a pretty massive regression see #1147170 and had to be dropped.
