Kerberos5 depends on gnupg but not gnupg2

Hello all, As I was reviewing and auditing my MacPorts dependency chain, I realized that the kerberos5 port depends on gnupg. However, gnupg seems to be a bit ancient and I would think deprecated by gnupg2. Would that be my imagination or is there a good reason to continue having kerberos5 depending on gnupg? Or is there a successor in MacPorts to kerberos5 which I may be unaware of? Much thanks, T.M.
