kismet-200710.r1 fails to build - FreeBSD 6.2-RELEASE

[Peter Thoenen]

I am pretty sure this builds fine on pointyhat and also builds fine on
my amd64 6.2 FBSD box (and also on CURRENT).  This was an issue awhile
ago but was patched a year or two pack.  Make sure you built base with
libpcap and its current (I believe the exact patch was pushed upstream
there) .... there was a recent closed PR about this ... I can dig up if
you wish.
