I wonder if someone smarter than I am could packagize No-IP.com's Dynamic
DNS update client?

The so-called "Linux" version compiles on all flavors of BSD; you can
download it here:

http://www.no-ip.com/downloads.php

(The documentation at http://www.no-ip.com/unixNotes.php says you have to
patch the source to make it build on *BSD, but that's actually no longer
true--see the comments in the source file noip.c.)

The FreeBSD ports collection includes it; see

http://www.freshports.org/net/noip/

The FreeBSD port maintainer seems to have written some patches for it, and
he made it so it runs under its own user/group id.  He also wrote his own
version of the startup/shutdown script (the Linux version doesn't work on
FreeBSD or NetBSD--at least the shutdown part doesn't).

It's a fairly simple program.  If anyone could turn it into a NetBSD
package, I'd be eternally grateful.

Thanks,
