Comment:

 Did you mean wxMaxima? I'm Cc'ing the maintainer of wxMaxima.

 The message "Expected in: /usr/local/lib/libPng.dylib" indicates you have
 a libpng library in /usr/local. MacPorts does not like libraries existing
 in /usr/local. Please rename /usr/local to /usr/local-off and try
 installing again and hopefully it will work. Then, reinstall everything
 you have in /usr/local-off using MacPorts, and then later you can discard
 /usr/local-off.
