Dont see php frontend after installation

[Damerson]

After installation do not see the php-frontend. Only a blank page.

System:
CentOS 5.5
Apache - 2.2.3
mysql - 5.0.77
PHP - 5.1.6

In httpd error log:

[Thu Dec 23 05:31:40 2010] [error] [client 79.164.95.69] PHP Warning:  require_once(include/config.inc.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in /var/www/dl_admin/data/www/stream-work.local/zabbix/index.php on line 22
