i ran into a possible explanation from this SO question that references trying to import opencv:

dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/cv2.so, 2): Library not loaded: /opt/local/lib/libtiff.5.dylib
    Referenced from: /opt/local/lib/libopencv_highgui.2.4.dylib
    Reason: Incompatible library version: libopencv_highgui.2.4.dylib requires version 8.0.0 or later, but libtiff.5.dylib provides version 6.0.0

perhaps matlab executes system calls in some way that links against its old versions of libraries rather than the up to date ones you have installed?

you don't say whether the script runs fine when executed from a regular shell?
