Yes... And I just solved my problem... The problem was actually trivial. I upgraded to development from FC3, so in my php.ini file, there was a reference to /usr/lib/php4. Changing that to /usr/lib/php/modules did the trick. Sorry for the noise :) And thanks for the helpfullness...
Umm. Actually, this may be a bug, or at the very least worth a release note. php.ini is a config file, and I doubt we can expect it to be updated when the RPM is updated.
