CakePHP 1.2 on Leopard 10.5.6

<VirtualHost www.cakeblog.dev>
  DocumentRoot "/Users/USERNAME/Sites/cakeblog"
  ServerName cakeblog.dev
  ServerAlias www.cakeblog.dev
  <Directory "/Users/USERNAME/Sites/cakeblog/">
    Options FollowSymLinks
    AllowOverride All
  </Directory>
</VirtualHost>

The line you add to /etc/hosts should be:

127.0.0.1   www.cakeblog.dev 

The tutorial is pretty accurate about how to set up PHP and MySQL.
