This has been fixed in the knock-0.3 ebuild (marked unstable), but not in knock-0.1. Here is the relevant part of the ebuild ChangeLog: 03 Jul 2004; <pyrania@gentoo.org> knock-0.3.ebuild: Depending on net-libs/libpcap. Closing bug #55131. Looks like someone is going to increase their fixed-bug-count quite easily... ;-)
I'm going to add it to -0.1 instead of marking -0.3 stable (which I would prefer), because of the non-blocking TCP patch of yours which I just committed.
