Include errors installing lastest version on PHP 5

[Dee]

Hi,

I have downloaded the latest version of Zen-Cart and attempting to install it on PHP 5.1.2 and running an Apache server. When I launch zc_install/index.php I get numerous errors about not finding include files (see the first such below).

I can fix all those errors, and thus coax the installation to complete. but launching the store produces similar problems.

There must be something basic I can fix somewhere that allows all scripts to find their include files correctly. Can someone who has a PHP 5 installation running please give me some pointers?

Thanks

If I update PHP's inlude path to the appropriate value in all three application_top.php files all include files are found.
