http://www.libgd.org/DOC_INSTALL_OSX is a good page on all the steps one needs to get GD installed for perl. Is it worth it? Time will tell.

Well, I am real late for work now. It turns out my Mac did not have automake-1.9.6, which caused all sorts of issues. I got that from here: http://ftp.gnu.org/gnu/automake/ more specifically here: http://ftp.gnu.org/gnu/automake/automake-1.9.6.tar.gz

Once I installed that, I got GD to make. Not pretty. Not pretty at all!
