I say that it does, but the version of libpcap is an old one, which
does not have pcap_sendpacket, this routine is a recent addition to
the library (recent means a few years here).  Note that there are no
complaints about all the other routines from libpcap...

You need to find a new version of libpcap.  www.tcpdump.org might be
a good place to start.
