An undate on the checker from Alexander Lehmann

Enhancements include zlib capability, which means you can print the line filters for each line of the image, information on the compression factor, extended support for printing palettes and support for all known PNG chunks. The checker also supports JNG images conforming to Draft 70 and partial support or MNG streams.

There are run-time dependencies that need to be installed first. Why not use depothelper to install them all in one go?
