ERROR: version of config(8) does not match kernel

[Kiffin Gish]

I've update my src directory, but keep getting the following error (see
below).

Yes I understand what it is saying, but how can I fix it?! I ran cvsup a
couple of times, but it doesn't seem to help.

Make sure that /usr/src/usr.sbin/config is in sync
with your /usr/src/sys and install a new config binary
before trying this again.

If running the new config fails check your config
file against the GENERIC or LINT config files for
changes in config syntax, or option/device naming
conventions
