[drupal-support] Installation problems

[Tib]

Everything went smoothly at first until it came time to point a web
browser at it and login.

-------------------------------
Warning: main(includes/database.inc) [function.main]: failed to open
stream: No such file or directory in

-------------------------------


By editing bootstrap.inc and removing the 'includes/' from the
database.inc, session.inc, and module.inc listings at the end I was able
to get to the next error - shown below.

------------------------------
Warning: db_set_active(includes/database.mysql.inc)
[function.db-set-active]: failed to open stream: No such file or directory
in /home/tib/public_html/drupal/includes/database.inc on line 116

Fatal error: Call to undefined function db_connect() in
/home/tib/public_html/drupal/includes/database.inc on line 122
------------------------------

Now what I'd like to know is if the first correction I made, by way of
bootstrap.inc, will screw up other things in a kickdown fashion.

Next how do I get around the database issue?

Finally - why is this happening to start with?

I'm running php5.0.4, mysql 4.0.24, and apache 1.3.27.

Thanks
