Sounds believable

original poster needs to run:

vlm at server:~$ nm /usr/lib/libpcap.a  | grep pcap_sendpacket
00000000000003b0 T pcap_sendpacket
vlm at server:~$ ls -al /usr/lib/libpcap.a

Thats what I get on my Debian-Stable-relese machine.

If grep on his machine finds nothing, then thats the problem...
