Hookais... I'm sure I've forgotten to do something...

I try to install the board and it just returns me to the install.php form, over and over again hmm Never reall uses any CPU after submitting the form data ~.~ I have lighttp web server, php5, and php5-sqlite all in a chroot jail and sqlite outside the jail. I ldd'ed php5 and such and got all the libs. Copied the /etc/php5 /usr/bin/php* /usr/lib/php5 directories into the jail. Then I did this:

$ tar -xhjf punbb1.2.12.tar.bz2
$ mv ./punbb1.2.12/<i forget? punbb i think?> /home/www-user/www/pages/music/forum
$ firefox ddns.hostname/music/forum/install.php

lighttp is chroot'ed to /home/www-user. Any request to ddns.hostname is served up with /home/www-user/www/pages as it's root. I stored the sqlite (v2.8.x) database in /home/www-user/data/db/music_forum.db (-rw-r--r-- 1 www-user www-user     0 2006-09-05 03:01 music_forum.db).

I entered this info into the "install.php" form:

DatabaseType: SQLite
Database server hostname: localhost
Database name: /data/db/music_forum.db (also tried ../../../../data/db/music_forum.db)
Administrator username: private
Password: *******
Conf Password: *******
Administrator's e-mail: private@private.private
Base URL: http://ddns.hostname/music/forum (also tried http://localhost/music/forum and http://localhost/www/pages/music/forum)

Anyone have any ideas? I sure it's not the permissions because lighttp ignores "execute" permissions (all files ending in ".php" are configured to be run by "/bin/php"; don't even need the #!/usr/bin/php line); also I do see the php file displayed as an html file and not as random php source. Thanks in advance.
