There was an update to subversion recently (1.7.x to 1.8.y).
If you updated the /usr/src tree with the new subversion
(i.e. svn upgrade; svn update), and then transferred that tree
to another machine that contains a non-upgraded subversion
client, if you build the tree there, you'll miss the r###### in
uname.

Upgrade your subversion client on the target machine, and,
optionally, run 'svn upgrade' on the source tree, then rebuild
and reinstall. uname -a should show r###### again.
