It is known bug - https://www.illumos.org/issues/2706

Currently I spend time updating JDS and not in fight with bloody libpng.
My vision is to build everything in JDS with libpng 1.4, to solve all
these problems.

If anybody has time for fixing SFE ImageMagick to build with older
libpng temporarily then he is welcome to prepare fix and I can push the
results to the repository :-)

Best regards,
