I already did re-install libgd after I read that thread even though brew showed freetype as installed. Didn't work.
The only thing I can think of is I did try installing GD with cpan before installing it with cpanm and it could not make so I force installed it. Maybe there's some leftover crap somewhere that is messing things up?
cpan -t GD
