Making gd Extensions

Greetings: I'm following the thread regarding PHP extensions in the thread "The future of PHP - accessory libraries" very anxiously. I've been trying to get this feature going for quite some time but without success. The current item I'm wrestling with is the gd extensions. I've rebuilt PHP and Apache so many times to enable one feature only to learn that I forgot to recompile one that I'd relied on previously. It's a never ending battle to get all of the features required. The .so extensions option is a great feature that I'd like to make use of. In trying to compile the gd .so extension (gd-1.8.4), I'm receiving the following errors. Any ideas?
