I'm asking for help with gd, which is a macport package. I already ask
on php-install list -- someone there suggested there might be missing
headers for gd.

Well, as noted in the thread from last week it looked a gd problem, then freetype, before it finally was resolved as kerberos/heimdal. If you really want help, it might be a good idea to provide some debug information other than where configure bails out. But if MacPorts says that gd2 is installed and the other ports that have dependencies on it work, you might be barking up the wrong tree.
