[Joe Corneli]

If I turn on png support when I build,

   Does Emacs use -lpng?...................................yes

then I get the appended error message.  Note, I just installed fontforge
before rebuilding Emacs, and after Googling it seems that most of the
messages involving the symbols in question are associated with that
program.

My crystal ball says that you somehow donwgraded your libraries to a
libpng version older than 1.5, while the headers are still for 1.5.
These functions are needed by Emacs for libpng 1.5 or later.

Thanks Eli - I've reported this to Macports, we'll see what they say.
