FreeBSD Port: devel/distcc

Hi all,

Does distcc use the /usr/local/etc/distcc/clients.allow file by default?
I ask because the default /usr/local/etc/rc.d/distccd file is set as follows:

```
distccd_flags=${distccd_flags-"-a 127.0.0.0/8 --user distcc --daemon -P /var/
run/distccd.pid"}
```

I was able to allow access to hosts in my network by adding "--allow 
2001:db8:3333:4444::/64"

Also, by default distcc seems to listen to IPv6 on port 3632, but not IPv4. Is 
that by design?

Thanks!
