Near the top of pcap.c you'll find this:

     #ifdef __linux__
     #define uh_dport dest
     #define uh_sport source

My guess is that "__linux__" is not defined for this compile
environment.

I'm not saying it should be.  I don't know the ways of Debian/kFreeBSD.
If there is another symbol that can be checked, we should include it
in the if statement.
