Sounds good – I’ll be happy to answer. I looked up the error message and it said that the newest version of libpng is more rigorous in what it’ll accept and that there is probably a malformed block in one of the png files that previous versions let through as a warning but the current version treats as an error.
I have a sneaking suspicion that I have a newer version of libpng floating around installed by something else I use that is newer than the one used by your library.
