See previous posts on the subject of using FreeBSD on Alpha. In
short, Alpha is no longer a Tier-1 platform for FreeBSD, and it
continues to decline. I would not be surprised if FreeBSD removed
all support for Alpha in the near future.
It was a nice dream while it lasted -- hot hardware with a great
OS. But that's the way the cookie crumbles.

You might want to see if you can build the release version of
ntpd-4.2.0, or one of the more recent ntp-dev tarballs for that
platform. There have been a huge number of improvements that have
been made in the code, and it doesn't really make any sense to be
trying to muck about with something that old unless you have no other
choice.
