The problem is caused because pcap_findalldevs is returning an address family 
value of 17
#define PF_PACKET       17      /* Packet family.  */
#define AF_PACKET       PF_PACKET
and the ghc Family datatype doesn't support it :-(

I've now fixed this, the fix will be in GHC 6.6 and future releases of 
the network library.
