[OT: sorry Matt, hit email instead followup twice... stupid me]

My bets are that the SIOCGIFADDR opcode has a different numerical value for
BSD. Even if some names are portable, the numerical values aren't! I don't
have BSD, but using 

find /usr/include -type f -name '*.h' | xargs grep SIOCGIFADDR /dev/null

should give some hints...
