PHP+Apache suddenly not working

I have no doubt that this is due to an update that was done on my system at some point, but unfortunately I can't pinpoint where. The upshot is that PHP is completely unresponsive for me when run from Apache and I'm not sure where to look. I recognize that this isn't an apache support list. This message is being cc'd there too. The system is FreeBSD 6.1-RELEASE-p15. PHP 5.2.11 from ports. The only error I get in my php log is this: [27-Oct-2009 13:05:00] PHP Fatal error: Call to undefined function preg_match() in /usr/home/foo/public_html/cerb4/libs/devblocks/libs/zend_framework/Zend/Cache/Backend/File.php on line 125 Now I've checked and double checked that pcre support is built into php. I'm not sure if there's a command that I can run in php to show all the extensions that are installed or something, but I'm a bazillion percent sure that it's there, so I don't believe that's the cause of the error. I'm reasonably sure of this because the preg_match error thrown every minute when a cron job runs, I have a .php that calls phpinfo() that shows a blank screen when hit from a browser. My problem is that I don't know how to troubleshoot this. I can seem to run PHP from the CLI just fine, so does this look more like an apache issue or perhaps some php module or extension that talks to apache?
