Problem with 1.2.1 upgrade

I converted over to 1.2.1 and my wordpress installation broke. So, I diffed my installation with the new stuff, removed any index/template stuff, and applied the changes one file at a time.
I’m running FreeBSD 5.3 patch branch with the following ports:
mathopd-1.5p3 A very small, yet very fast HTTP server
php4-cgi-4.3.9 PHP Common Gateway Interface
php4-mysql-4.3.9 The mysql shared extension for php
php4-pcre-4.3.9 The pcre shared extension for php
I’ve tried both updating my wordpress 1.2.0, and using a clean unzip with just my wp-config.php file copied over, neither worked.
So, here’s a diff of the changes that are causing problems:

Applying everything else that 1.2.1 changes doesn’t affect my installation, but that diff does. If you go to <http://test.weller-fahy.com&gt; you’ll see a broken installation, <http://weller-fahy.com&gt; is working (without the above patch).
Anyone have any suggestions?
