[Debian-astro-maintainers] Bug#1059970: fitspng: autopkgtest regression in testing

[Filip Hroch]

Dear Graham,

I think the fail is result of linking of different versions of zlib via
dependent libraries.

Correct me, if I'm wrong, fitspng has the dependences:

 Build-Depends: debhelper-compat (= 13), libcfitsio-dev, libpng-dev

zlib is indirectly linked via both libraries.

Currently, in unstable, libcfitsio-dev runtime depends on libcfitsio10,
which depends on 

 zlib1g (>= 1:1.1.4)

while, libpng-dev on zlib1g-dev so

 zlib1g (= 1:1.3.dfsg-3)

The status is a little bit complicated, libpng16-16 has also
dependence on zlib1g (>= 1:1.2.11.dfsg).

I have no idea how to solve the trouble, and if it is solvable
due potential dependence both the libraries on a particulal
version of zlib.

Regards,
FH
