Your experience is similar to mine. I am not in the employ of Zymkey but have documented my findings and submitted the experience.

You create usr/local/lib folders in usr/lib/python2.7/dist-packages then it seems like
usr/lib/python2.7/dist-packages/usr/local/lib .
Then copy libzk\_app\_utils.so file from usr/local/lib and paste it in usr/lib/python2.7/dist-packages/usr/local/lib then test.
