After building 288 packages some intermediate result: 288 built 85 failed 200 built ok (3 currently rebuilding due some BD needed to be rebuilt themselves too) Short analysis of the build errors are on this titanpad: https://titanpad.com/libpng16-transistion I will continue update the pad with new results. To build the packages, I modified the libpng16 package from experimental to provides also libpng-dev and libpng12-dev. -- tobi
