OK, that means that the MacTeX distribution has a really really outdated
version of libgd. It is using the truecolor-incapable libgd1.x which has
been replaced by the truecolor-capable libgd2.x, I dunno, 5-6-7 years ago.

The incanatation I sent you will work.

But the best course of action would be to rebuild dvipng against libgd2.
And to recommend the distributor of MacTeX to do so too. (Perhaps I
should just remove the compatibility code and force everyone to go libgd2.)
