Blog plugin doesn't work due to django.contrib.markup deprecation

Hi all, I'm trying to use blog plugin on site hosted on gh-pages and I get the following error:

$ cactus serve

In https://docs.djangoproject.com/en/1.7/internals/deprecation/ the django.contrib.markup was deprecated in Django=1.6 while pip install cactus installer Django=1.6.1

How to around the issues?

    ========
    WARNING!
    ========

    You have just installed Django over top of an existing
    installation, without removing it first. Because of this,
    your install may now include extraneous files from a
    previous version that have since been removed from
    Django. This is known to cause a variety of problems. You
    should manually remove the

    /usr/lib/python2.7/dist-packages/django

    directory and re-install Django.
