ImportError: Stubs not compatible with omniORBpy version 4.2.

I am trying to run OMPython on mac. I installed OMPython through pip and omniORB packages through homebrew. I am able to import OMPython but when I use OMCSession I get an error saying "omniORBpy version 4.2 expects stubs version 4.2. Stubs in /usr/local/lib/python2.7/site-packages/OMPythonIDL/omc_communication_idl.pyc are version 3.0 (rev 0)".
