Occasionally I ran into similar problem. I guess I'll be forgiven for replying so outdated post, but it seems no answer was given yet on the forum.
The problem is in changes between libpng12 and libpng14. You'll get this error on system with libpng>=1.4.
To fix this fast you need to replace info_ptr->trans_values with info_ptr->trans_color and info_ptr->trans with info_ptr->trans_alpha in mod_map/file_png.c

see patched file_png.c for revision 244 in attach
