PHP problem or MySql problem , maybe both?

[reddog]

I've been trying setup apache, mysql, php, and phpmyadmin on a linux box here at home. I have apache up and running, that one is easy. MySql is also running and has a root user and password set. Php is working as far as i can tell, at least the phpinfo() script says so. phpMyAdmin is working fine as well, and as far as i can tell is connecting to the database. So i loaded up nuke7.5 for testing, installed the sql for 7.5. However when i go to http://mysite.com/index.php, i get the following errors:


Warning: main(db/mysql.php) [function.main]: failed to open stream: No such file or directory in /srv/www/htdocs/db/db.php on line 53

Warning: main() [function.include]: Failed opening 'db/mysql.php' for inclusion (include_path='/usr/share/php') in /srv/www/htdocs/db/db.php on line 53

Fatal error: Cannot instantiate non-existent class: sql_db in /srv/www/htdocs/db/db.php on line 86



Coincidentally, when i run the phpinfo(). Under the MySql section the following values read like this:


MySql Includes = "No Value"
MySql Libs = "No Value"
MySql_Modules_Type = "None"



I'm thinking i missed something in one of the config files, and I've gone over it many times. But the errors throw me off, because i don't know diddly about php. So i was hoping one of you gurus could interpret what the errors mean.Thanks in advance for any replies !!

Here are a few more specs:
Suse Linux 10.0
Apache2 - 2.0.54
MySql - 4.1.13
PHP4 - 4.4.0
phpMyAdmin - 2.7.0 -pl2

btw, here is a copy of db.php
