Error after upgrade from rails 3.1 to 3.2.6 - ruby-on-rails

Question

I set myself the task of upgrading my app from rails 3.1 to rails 3.2.6 on my local mac book air lion dev environment. I followed this guide and ruby is upgraded, and all of my gems seemed to install and rails -v gives the answer of rails 3.2.6. If I run any rails commands though, e.g. rails c to start the console, I get this:
MacBook-Air:myapp bob$ rails c

Yes I do use pubnub in my app - it's always been working fine so I don't suspect it necessarily is the problem.
The application.rb line 13 (might be not be relevant) is
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require *Rails.groups(:assets => %w(development test))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
I do precompile assets before deploying.
The /Users/bob/.rvm/gems/ruby-1.9.3-p0#rails32/gems/pubnub-ruby-0.0.9/lib/pubnub-ruby.rb:1 file is present and I opened it fine.
Does anyone know whats going on / is it pubnub specific or something else? I'm not sure how to troubleshoot further and googling hasn't brought anything up so far.
Thanks,
Dave

I don't see the file pubnub-ruby.rb in the repo for that gem. Try running $ bundle install or $ gem update pubnub-ruby.
