First time cake user and I'm having real apache problems. For some reason the .htaccess is trying to find

File does not exist: /Library/WebServer/Documents/Users

but there is no such directory as Users. I have tried setting up the following also:

/etc/apache2/extra/httpd-vhosts.conf

<VirtualHost *:80 >
DocumentRoot "/Users/username/Sites/mysite/app/webroot"
ServerName mysite.dev
ServerAlias www.mysite.dev mysite.dev *.mysite.dev
<Directory "/Users/username/Sites/mysite/app/webroot">
    Options Indexes FollowSymLinks
    AllowOverride All
</Directory>
</VirtualHost>

/etc/hosts

127.0.0.1   mysite.dev

/etc/apache2/users/username.conf

<Directory "/Users/username/Sites/">
    Options Indexes MultiViews FollowSymlinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

That also hasn't worked, but with a different error Failed opening required 'cake/libs/cache/file.php'

Although I'd rather not use virtual hosts, and just run it off localhost
