PHP 4.02 Installation: gd.h not found

[Anon]

Hello,

I am installing PHP 4.02 on FreeBSD and run into the following error, I have pasted a brief section around which the error happened:
/usr/tmp/php-4.0.2/ext/gd/php_gd.h:33: gd.h: No such file or directory

The file gd.h is not to be found in the distribution also, can somebody help me?

Thank You,
Sam

This is not that crucial, but since I was upgrading Apache, I thot I might get PHP upgraded as well. Is it necessary to recompile PHP if you want to upgrade Apache. Will copying a new httpd binary upset the PHP settings for the earlier apache installation?

Thank You,
