'version' directive on BIND 8.4.5

[Huiqi_Liu at veritasdgc.com]

How do I use the "version" directive to block "version.bind" queries?

I tried various things but it complains about syntax error:

For example,

options {
        directory "/usr/local/named";
        .....
        version 8.4.5-REL ;
};

Thanks!
