We have to chase the checksum so the port still works. But we (the
FreeBSD security community) need assurances that the change was benign
and not a trojan introduced by a compromised server, and the ports
community needs assurances that the software functionality has or has
not changed significantly. Sure, it's bad release engineering for an
author to do the latter, but it happens and we have to deal with it.
