OK, so I've just verfied that Frozen-Bubble-1.0.0e does indeed  
install libpng.3.dylib as a framework, and running otool on this gives

otool -L  /Volumes/Frozen-Bubble/Frozen-Bubble.app/Contents/ 
Frameworks/libpng.3.dylib
/Volumes/Frozen-Bubble/Frozen-Bubble.app/Contents/Frameworks/libpng. 
3.dylib:
         @executable_path/../Frameworks/libpng.3.dylib (compatibility  
version 3.0.0, current version 3.0.0)
         @executable_path/../Frameworks/libz.1.dylib (compatibility  
version 1.0.0, current version 1.2.2)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0,  
current version 71.1.1)

So it sounds like this may indeed be the offender, but why does DYLD  
find it?
