django-haystack spatial search requirements?

Question

I'm trying to use django-haystack for geo spatial queries as described here: http://django-haystack.readthedocs.org/en/latest/spatial.html I'm using elasticsearch as backend. I created search_indexes according to documentation, configured django and when I tried to use rebuild_index management command for the first time I saw an error:

python manage.py rebuild_index --settings=myproject.settings.local

WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.

    from django.contrib.gis.geos import Point
ImportError: cannot import name Point

Point which is used by haystack for spatial searches from django.contrib.gis.geos cannot be imported and I'm not sure why. Is a full working django.contrib.gis (geodjango) a requirement for spatial search in haystack? In other words: must I install all c libraries for geodjango, configure postgis and only after that i can use a Point class in haystack?

I resolved the problem by installing libgeos and libgeos-dev

sudo apt-get install libgeos-dev
