kerberos5 @1.7.2 fails to perform a livecheck

[nonstop.server@…]

Port kerberos5 fails to perform a livecheck.

% port -v livecheck kerberos5     
Error: cannot check if kerberos5 was updated (The requested URL returned error: 406)

Setting variables livecheck.regex, livecheck.type, and livecheck.url solves the error.

% port -d livecheck kerberos5
DEBUG: Changing to port directory:

kerberos5 seems to have been updated (port version: 1.7.2, new version: 1.10.1)

A difference report of the Portfile is attached.
