Yes, just link GDAL with a copy of libpng that is not in a system location.
Py2app won't include files in system locations into the application bundle, and
uses dependency information in the binaries to locate the libraries it should
include. That dependency information contains the full path to the required
shared libraries, just having a copy of libpng12.0.dylib will therefore not
work but you have to link libgdal to that copy.
