Ah, that explains it. I last synced 3 days ago Obviously, updating libpng in the tree was a two stage process, with a longer than expected delay between them. Or maybe a bug the dev didn't anticipate showed up right away and needed fixing. You and fortitude both sync'ed in this middle period and got hit by the bug.
