[PHP-INSTALL] php -m shows gd but can't use imagecreate

[Chris]

Hello,

     I am trying to use the GD library and I don't care which one I
use(bundled or non).  I have issued the php -m and have seen the module
in the list.  Why do I get an error message when trying imagecreate?
I am using php-4.3.3.  I can provide more details if need be.
