This seems to be due to the recent upgrade of libpng to version 1.5. There's a patch at http://www.pkgbuild.com/~ioni/libpng-1.5/pgplot- libpng15.patch which should do the trick. I'm not sure what the correct attribution for that patch is, though -- it looks like http://www.pkgbuild.com/ is associated with Arch Linux, but nobody is directly claiming credit. -- Ticket URL: <https://trac.macports.org/ticket/35945> MacPorts <http://www.macports.org/> Ports system for Mac OS
