Trying to install on local test server and getting this message in browser:

Warning: require(../includes/classes/class.base.php) [function.require]: failed to open stream: Permission denied in /srv/metro/www/zencart/zc_install/includes/application_top.php on line 29

Fatal error: require() [function.require]: Failed opening required '../includes/classes/class.base.php' (include_path='.:/usr/share/php:/usr/share/pear') in /srv/metro/www/zencart/zc_install/includes/application_top.php on line 29

I had set all permissions as per the instructions.
The file ../includes/classes/class.base.php does not appear to be there. I downloaded again and still cannot find it. Also tried from a different mirror.

zen-cart-v1.3.6-full-fileset-10272006
Ununtu 6.10
MySQL - 5.0.24a-Debian_9-log
phpMyAdmin - 2.8.2-Debian-0.2
apache 2.0.55
php 5.1.6

Tried copying full functioning cart directory from server to local, but when entering via browser it automatically tries to go to zc_install which does not exist. (cpanel install).
