Just find the header file that defines sa_family_t and include it in the
source. This is a common problem with updating older ports. To make stuff
compile on many platforms, there are a lot of new "types" of objects being
defined. I remember way back where there was almost a WAR over the 
introduction of "size_t". Get used to it!

Cheers,
