Bug#809944: gargoyle-free: FTBFS with libpng16

[beuc at debian.org]

Hi,

Can you provide some more details about this transition / the build
issue, because I can't figure it out ?

- trying to install libpng16-dev yields mass incompatibilities with
  base packages such as libSDL and gtk2

- the pad refers to "FTBFS undefined reference to `set_var'" which I
  can't find in the build log

- the build log says it's killed by timeout after what appears to be a
  successful build (using libpng12-dev)

- gargoyle-free build-depends on libpng-dev already.

Cheers!
Sylvain
