Hi,
   I notice that if you have USE_INET6=no defined in /etc/mk.conf, the pkg
options subsystem says that it is a deprecated variable, but I'm not sure
that it is, exactly?

It is used in various places in the NetBSD userland build to control
wether inet6 capability is compiled in (libc for example)

Well, I'm not sure if its a question or just a grumble.
