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 -- F.
