This (presumably) isn't really a WordPress problem, but I thought I might get a better/quicker response here than elsewhere. I had WP up and working fine with apache_mod_php4 (4.3.6, I believe it was) and mysql 3.23, but then got the bright idea to upgrade mod_php4 to the latest version (184.108.40.206). After doing so and restarting apache, I now get a message from WordPress stating that my php installation appears to be missing the mysql required to run it. I restarted the mysql server, and nothing. I upgraded it to the very latest 3.23, and nothing. Where did I screw up? This is all being done under FreeBSD v4.9, using the ports collection.
