Your src tree is not checked out properly. This usually happens because
at some point in the subversion 1.6 days you used devel/subversion to
check it out, rather than devel/subversion-freebsd. Fortunately, the new
version of devel/subversion has the option to include the
FreeBSD-specific bits, enabled by default. So, to fix this problem:

1. 'svn diff' your src tree, save any local patches.
2. rm -rf /usr/src
3. Upgrade devel/subversion, make sure that the first 3 options are
4. Check out the new src tree, re-apply any local patches
5. Run mergemaster again. Make sure to merge the new $FreeBSD Ids.

The 'CVS Id' is a remnant of the pre-svn days. I haven't changed it in
case someone has a script that parses the output.

Maybe. It's lasted as long as it has without anyone getting confused.

So don't read it. :)
