Hi,
I uploaded libpng 1.5.2 to experimental.
libpng maintainers plan to transition from libpng 1.2 to 1.5.
I am checking build it the package depend to libpng.
I noticed your package FTBFS by libpng 1.5.
I created the patch that revise this problem.
Could you check and apply this patch?
Best regards,
Nobuhiro
