I get the following error building from sources that were cvs updated
just an hour ago.  The error occurs on port-mac68k, port-i386, and
port-alpha.  (Probably happens everywhere else, too, but those are the
only arch's I have to check.)

All kernels are configured _without_ INET6 but _with_ PULLDOWN_TEST ...

Seems to me that since the comment in the GENERIC kernel config files
for PULLDOWN_TEST says it should work for IPv4 and IPv6, it should 
work for IPv4 only.
