You need to force linking against the newer version. It's easier to do
this if you link against libpcap statically.

See the FreeBSD port of tcpdump for one way to do this -- the configure
script will prefer to look for an untarred and built libpcap source
tree in its parent directory.

However, if you're using dynamic linking, all bets are off, unless you
change the -rpath option during linking.
