gd2 on the mac

[sansid3]

phpinfo()
PHP Version => 4.3.2
Mac OS X, 10.3.4

phpinfo() does not refer to gd at all

the php manuel says to use
gd_info but
php -r 'gd_info()';
does not work from the terminal line.

I have uncommented
extension=php_gd2.dll
in etc/php.ini file

I have not found this file nor
gd.so anywhere on my mac.

so I don't know what directory to put, I tried the
default "./" and this one

; Directory in which the loadable extensions (modules) reside.
extension_dir = "./extensions"

Any mac person who knows what to do?

I upgrade to php 4.3.6

gd now appears in the config page.
