EnderX 352 Posting Shark

I'm still trying to install PHP. I used a different set of configuration commands, ones that more closely match the set that the old setup had on it, and I've run into a different problem. It configures, it builds, and then when I try to restart the server I get the following error message:

"Syntax error on line 113 of /etc/apache2/httpd.conf:
Cannot load /usr/lib64/apache2/libphp5.so into server: /usr/lib64/apache2/libphp5.so: undefined symbol: php_session_create_id"

The line in the conf file is the loadmodule line for the php 5 module. The .so file, when I opened it, contained what appeared to be mostly system gibberish; I'm kind of scared to mess with it.

Anyone have any reasonable suggestions for what might have caused this, and if so, would you please share them?

Thank you for your consideration,
