I'm getting this error & I understand that I need to symlink some file

inside the chroot (/var/www) area but I'm not sure which file to be

exact. I search previous misc@ archive but they seem a bit confusing.
Warning: dl() [function.dl]: Unable to load dynamic library

'/var/www/lib/php/modules/mysql.so' - File not found in

/mysite/mediawiki/install-utils.inc on line 17

Could not load MySQL driver! Please compile php --with-mysql or

install the mysql.so module.
Here are the necessary packages installed -
# ls /var/db/pkg |grep php

php5-core-5.1.4p1

php5-gd-5.1.4

php5-mysql-5.1.4
I noticed that if I get out of chroot mode mediawiki works fine. That

is, if I do
# apachectl stop

# httpd -u

# apachectl start
it works fine
I have "/var/www/var/run/mysql/" owned by _mysql:daemon.
Any kind of help would be appreciated.
