I was working on a port makefile for netdumpd before this thread
started. :)

It would be a bit more usable as a port; I prefer it that way since
Isilon's infrastructure folks would like to run netdumpd on 11.0.
For what it's worth, I've got my revision of the code here:
https://github.com/markjdb/netdumpd

This version fixes some performance problems in the original, and runs
most of the code in capability mode. The capsicum integration hasn't
yet been reviewed, however.
