Re: undefined reference to png_...

No, it doesn't appear to be linking to png. The extra output is as follows:

Making all for app WindowApp...
gcc  -rdynamic       -fgnu-runtime -o WindowApp.app/./WindowApp \
        ./shared_obj/MyApp.o  -LGNUstep/Library/Libraries 
-L/usr/local/lib/GNUstep/Local/Library/Libraries 
-L/usr/local/lib/GNUstep/Network/Library/Libraries 
-L/usr/lib/GNUstep/System/Library/Libraries -lgnustep-gui -lgnustep-base 
-lpthread -lobjc -lm
