Otherwise you get a ton of these:

sendto in send_ip_packet: sendto(6, packet, 40, 0, 127.0.0.1, 16) =>  
Invalid argument

Still checking out the rest of the functions, this one just made  
anything but connect scanning impossible. This may break PPC OSX but  
I don't have one to play with and try. Hooray for endians!

Compiled with i686-apple-darwin8-gcc-4.0.1.
