Unfortunately make for bind9.16.11 stops with 
exec: /usr/local/bin/autoreconf-2.69: not found

The same error has been presented by at least one other port.
There does exist a /usr/local/bin/autoreconf but it's a link 
to nowhere. There does exist /usr/ports/devel/autoconf, but
that stops make with
configure: error: Perl 5.006 or better is required
 

If somebody knows a fix or workaround please post!
