The output from phpinfo is listed below and shows no traces of other
ini-files than the default.

Configuration File (php.ini) Path
	/usr/local/etc
Loaded Configuration File
	/usr/local/etc/php.ini
Scan this dir for additional .ini files
 	/usr/local/etc/php
Additional .ini files parsed
	/usr/local/etc/php/extensions.ini

It only seems to be loaded once.

You are correct Jeremy. Commenting out zlib.so removes the warning and
zlib still shows up as a loaded module when I do php -i.

Can I provide any further tests or information for you?
