Error: The 'elasticsearch' backend requires the installation of 'requests'. How do I fix it?

I´m having a issue when I ran "python manage.py rebuild_index" in my app supported by haystack and elasticsearch.

Python 2.7 Django version 1.6.2 Haystack 2.1.0 Elasticsearch 1.0

Please see the error that is appearing:

I've installed all the packages needed to run those apps however is asking about requests, What is it about?

If you just install requests module through pip this error should go away.
