Bug#741901: antigrav: FTBFS with libpng16

[Nobuhiro Iwamatsu]

Source:  antigrav
Version: 0.0.3-5
User: libpng at packages.debian.org
Usertags: libpng15-transition

Hi,

libpng maintainers have a plan transition of libpng16[0].

libpng16 is already installed in experimental, and we are re-building
the package depending on libpng16.
As a result, we checked that your package was FTBFS.
Would you check also in your environment?
And if you could confirm problem, could you fix this?
