When I have had problems with libpng, it has helped to do "brew install
pkg-config". If you happened to start building Sage and then upgraded
Homebrew and/or Xcode in the middle of that, or if you've installed any new
Homebrew packages, you should probably start over with "make distclean"
followed by "make".
