Comment(by jmr@…):

 Replying to [comment:3 ryandesign@…]:
 > This looks like [http://sourceforge.net/apps/trac/vxl/ticket/71 upstream
 bug report 71] about incompatibility with libpng 1.5. This is strange
 because MacPorts has libpng 1.4, not 1.5, at least until we address
 #28385. Can you explain? Do you have a copy of libpng 1.5 on your system
 somewhere, perhaps in /usr/local? If you clean and try again and attach
 the new complete main.log it might provide more clues.
 There's no mystery, the log clearly shows that the declaration comes from
 `/Library/Frameworks/UnixImageIO.framework/Headers/png.h`. A complete log
 would still be nice of course.
