Hi MichaelH,
Thanks for the reply.
The php package for CentOS adds the AddType line, as well as LoadModule line for module_php4, to a file called /etc/httpd/conf.d/php.conf It looks like apache is loading configuration options from that file properly — I tried adding the lines in question directly to httpd.conf, and I still had the problem after restarting httpd.
The really weird thing is that index.php runs just fine. It’s just install.php (so far) that has the trouble. I initally thought that it might be a permissions issue w/ the wp-admin directory, but wp-admin/index.php _also_ works.
It feels like I’m running into some sort of overzealous security measure in CentOS. I have a post up at the CentOS forums as well as here, but thus far haven’t had any luck with finding answers …

You probably need to install the MySQL client on the webserver.
Dropping to a terminal and typing “apt-get install mysql-client” should do the trick.
