安裝phpmyadmin問題

安裝myphpadmin時的問題，用port裝，有cvsup過port
請問一下該如何解決？謝謝

checking whether to enable embedded MySQLi support... no
mysql_config not found
configure: error: Please reinstall the mysql distribution
===>  Script "configure" failed unexpectedly.
Please report the problem to [e-mail] [maintainer] and attach the
"/usr/ports/databases/php5-mysqli/work/php-5.0.4/ext/mysqli/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. an `ls /var/db/pkg`).
*** Error code 1

Stop in /usr/ports/databases/php5-mysqli.
*** Error code 1

Stop in /usr/ports/databases/phpmyadmin.
