They are owned by wwwlive:wwwlive. .svn/lock doesn't exist. It's
created by svn as part of the update process. The error I'm seeing is
due to the fact that, for some reason, I don't appear to have write
permissions on /www/live/.svn when running the setuid program as alexd.
Additionally, if I 'chmod -R o+w /www/live', everything works great.
Of course that totally defeats the whole purpose, so its not really a
solution. But it seems to make it clear that I'm having a
file-permissions problem.
