Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
Make sure the PNG format has a mode of rw- and it displays the PNG delegate library version number. If not ImageMagick was built without the requisite PNG delegate library which is required to read/write PNG images.
You need to check carefully the config.log file produced by the ImageMagick configure script to determine why ImageMagick failed to validate your PNG library. Perhaps its a permission problem or it could not find the header files.
