Comment(by ryandesign@…):

 MacPorts libpng 1.2.35 does provide libpng12.dylib version 36.0.0:

 {{{
 $ otool -L /opt/local/lib/libpng12.dylib
 /opt/local/lib/libpng12.dylib:
         /opt/local/lib/libpng12.0.dylib (compatibility version 36.0.0,
 current version 36.0.0)
         /opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current
 version 1.2.3)
         /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current
 version 1.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 88.3.9)
 $
 }}}

 So, for some reason, libgtk is not using MacPorts libpng but some other
 libpng. Some suggestions:

  * Where else do you have libpng on your hard drive -- perhaps you have
 another copy in /usr/local or /sw? ("`locate libpng12.dylib`" can tell
 you.) Try removing them.
  * Do you have the environment variable DYLD_LIBRARY_PATH set, thus
 telling software to first look for libraries in another location? ("`env |
 grep DYLD`" can tell you.) If so, try unsetting it.
