What is the expected output? What do you see instead?

ImportError: cannot import name Library

What version of the product are you using? On what operating system?

Ubuntu 14.04, python 2.7, setuptools 5.7

Please provide any additional information below.

From stackoverflow: In recent version of setuptools, Library is inside of 
extension.py. pyopencv should import Library as setuptools.extension.Library 
not setuptools.Library
