7.0, make buildworld without contrib. old top binary in contrib.

[peceka]

Hi,

can someone tell me if there is any possibility to do make buildworld
without compiling all contrib/ directory? I don't need for example bind9
in base, ipfilter, lukemftp(d).
And why in /usr/src/contrib is very old top binary, 3.5beta12? On
http://www.sourceforge.net/projects/unixtop there is top-3.7beta2 where
ie. -c option, very helpful, works.

Regards,
p.
