Installing/compiling GD?

Hi all, I am using a piece of open source software that fits perfectly with my needs on a current project. My problem is that it requires GD to be installed in order for me to use it. I am a bit of a novice at recompiling PHP to include modules and would appreciate some help if you don't mind? I guess my question is.. what exactly do I do? Lol. I look at my phpinfo() and I see that PHP was not compiled with GD. I look at my compile line in phpinfo and this is what I have: './configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-xml' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-magic-quotes' '--with-mysql' '--with-pear' '--enable-sockets' '--enable-track-vars' '--enable-versioning' '--with-zlib' Part of my question is when I go to recompile PHP, do I have to use the above configure commands IN ADDITION to the GD commands or JUST the GD commands? Any help? Thanks so much!! Aaron
