Many thanks to Kevin Grover for pointing out the following correction:

Page 33, Section 3.4.2 "Setting up Access"

These URLs:

http://svn.example.com/srv/svnrepositories/repos_uno
and
http://svn.example.com/srv/svnrepositories/repos_dos

SHOULD BE

http://svn.example.com/repos/repos_uno
and
http://svn.example.com/repos/repos_dos

to be consistent with the httpd.conf snippet.

As you can see, the site has been changed drastically. After getting hacked, I've decided to switch completely from Pivot to Drupal. So far, I've moved over some of the content, but not all of it.
