tcptraceroute/libnet11 fails under 10.4.5 on Intel platform

[dsinn@…]

tcptraceroute reports a failure when attempting to trace to a site:

fatman:~ dsinn$ sudo tcptraceroute www.seanet.com 80 Selected device en1, address 192.168.42.241, port 59746 for outgoing packets Tracing the path to www.seanet.com (64.38.166.88) on TCP port 80, 30 hops max libnet_write failed? Attempted to write 40 bytes, only wrote -1

This occurs via both en0 and en1.

Both libnet11 and tcptraceroute build fine:

I have no other installed port's that rely on libnet11, so I am unable to test if it is tcptraceroute or libnet11 that is failing. The system is a MacBookPro running 10.4.5.
