Build hasn't quite finished yet (various ports were hidden behind
webkitgtk which I've just fixed on i386) but it's not too far off now -
only fallout so far is www/squid:

Eui48.cc:364:19: error: variable has incomplete type 'struct arpreq'
    struct arpreq arpReq;

used for ARP-based ACLs for proxy clients on the same subnet as the
proxy - it's behind a #if targetting specific OS types so can be
disabled pretty easily. (I don't expect this is a particularly useful
ACL type - if a client can change their IP address to get around ACLs
they can probably change their MAC address too..)
