Installation issue with protobuf and caffe

[Wanderer]

From the last 2 days, I have been trying to install caffe on OSX 10.10

I was able to run all the installation commands successfully for caffe but when I tried to import caffe in ipython I got the exact same error: https://github.com/BVLC/caffe/issues/2092

So, as suggested in the thread, I tried to downgrade protobuf from 3.0.0 to 2.6.1. I was successfully able to install protoc and the new version does say 2.6.1

But now I not able to install protobuf python library. I am following the instructions mentioned here: https://github.com/google/protobuf/tree/v2.6.1/python I get the following error while running the command python setup.py google_test:

from google.protobuf import descriptor_pb2
