Ah ok, I think this is because libpng16-dev doesn't provide libpng-dev so any *-dev package depending on libpng-dev will use libpng12-dev. This is the package Tobias Frost posted which has libpng-dev enabled: https://libpng.sviech.de/libpng_package_used/libpng1.6_1.6.19-1.dsc This thread has the link (+ some discussion): https://lists.debian.org/debian-devel/2016/01/msg00159.html James
