Answer 1

The problem is you are using an outdated version of OmniAuth (0.3.2). Upgrade to version 1.x to fix this. See: https://github.com/intridea/omniauth

Note that there are several breaking changes from 0.3.2 to 1.x, so please read the upgrade instructions carefully: https://github.com/intridea/omniauth/wiki/Upgrading-to-1.0

Update: As part of this upgrade process you should remove the oa-oauth reference from your Gemfile.

Update 2: My warning about reading the upgrade instructions carefully was not thrown in there haphazardly: This is not an entirely trivial upgrade, care will have to be taken to make it work
