A guess would be that your PNG library is old and that the PNG_
macros are not defined in png.h. But new enough that configure thinks
it is usable.

You might try turning off PNG support by commenting out

#define HAVE_PNG 1

in src/include/config.h after running configure. That would give you a
running R (hopefully) but obviously no support for .png bitmaps.
Otherwise maybe install a newer libpng &al.
