[Pythonmac-SIG] Py2App libpng12.0.dylib

[Jay L.]

List,

Using py2app to bundle scripts which depend on GDAL (libgdal.1.dylib).
 Gdal, in turn, depends on libpng12.0.dylib.  On my build machine the
bundled app works wonderfully.  On another machine I am receiving an
"Incompatible library version" error, specifying that libgdal.1.dylib
requires libpng12.0.dylib required version 47.0.0 or later.
 /usr/X11/lib/libpng.12.0.dylib provides version 45.0.0.

Can I manually include the correct version of libpng12.0.dylib, bundled
with my app?

Build machine:
OSX 10.6.8
Python 2.7 64-bit installed via Homebrew

Testing Machine:
OSX 10.6.7
System Python (not that that should matter, because my 64-bit python should
be bundled)

I tried adding the frameworks option to setup.py, but without success.  I
added another libpng12.0.dylib that was on my system.

My setup.py:

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup

PACKAGES=['osgeo']

APP = ['PyStretch.py']
DATA_FILES = []
OPTIONS = {'compressed':True,
           'packages': PACKAGES,
           'frameworks':['/isis3/isis/3rdParty/lib/libpng12.0.dylib']}


setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

Any insight appreciated,
Jay
