 After installing gnats, I discovered that any attempts to connect to the
 gnatsd resulted in two log file entries in syslog that look like this:
 May 11 15:23:34 gaia gnatsd[13743]: connect from ::ffff:192.168.19.254 
(::ffff:192.168.19.254)
 May 11 15:23:34 gaia gnatsd[13743]: ?: bad address family 10 
 
 Upon looking up where this line came from, it appears to be because the
 incoming socket is being treated as if it is AF_INET6 rather than
 AF_INET, which is what gnatsd is expecting.  I conclude that this is
 happening on my system because it is set up with IPv6 addresses as well
 as IPv4 addresses.
 
 I have patched my local copy to accept connections with an address
 family of AF_INET6 and to look the name up properly.  If I can figure
 out how to do it, I'll attach the patch.
