We are working our way through the problems the libpng 1.4 upgrade has exposed. If you want to help speed this along, follow the instructions MacPorts printed when the build failed, which tell you how to file a helpful bug report. This would include providing the main.log file which contains the complete log of what happened. For the record, graphviz installs fine for me with the latest libpng.
