The template in geonode-project is not up to date with geonode master (aka 2.4dev).
You should use a template adapted for v2.4 like this fork of simod.
To launch a dev server once the template is installed just cd to the folder and launch:
python manage.py runserver
To "install" your new template project
python setup.py install
BTW, usually is better configure a virtualenv to develop python apps and not use sudo
