Looks like i had to upgrade python setuptools to address the above error. But now running into another issue while installing libffi-dev

Hey @kunalvjti, this seems to be an issue with raspian itself and not necessarily our samples / client library. This question is better suited for stackoverflow where more people who have expertise will be watching. I'm going to close for now, but if you run into issues after you get through this let us know.

Thanks. I got this resolved. Was missing a 'apt-get update' step :)
