2. Django 1.3 - a Python web framework
3. MySQL - you are recommended to download the dmg
4. MySQLDb - a Python-mysql connector
5. Photologue - a photo management plugin for Django
6. PIL - Python Imaging Library
7. oauth - Python oauth library
8. openid.consumer
   
9. Massive coupon's source code

Installation steps:

1. install mysql by running the dmg package
2. login to mysql by: mysql -uroot
3. mysql> create database massivecoupon;
4. mysql> create user 'massive'@'localhost' identified by 'coupon';
5. mysql> grant all privileges on massivecoupon.* to 'massive'@'localhost';
   
6. install every required modules by: sudo python setup.py install
   
7. untar massive coupon's source code and then update the settings.py file accordingly
   
8. run: python manage.py syncdb
9. run: python manage.py runserver
10. remove this line from massivecoupon/engine/forms.py:
    

    from massivecoupon.libs import formutils

11. go to browser and http://localhost:8000/admin

DEBUG = True

DATABASE_ENGINE = 'mysql'
DATABASE_NAME = 'massivecoupon'
DATABASE_USER = 'massive'
DATABASE_PASSWORD = 'coupon'
DATABASE_HOST = 'localhost'
DATABASE_PORT = '3306'

Notes:

• It is very important to install every required python modules completely, otherwise the applications won't run at all.
• Need to stop and re-run the manage.py runserver after every installation of modules
• It's also required to create a soft link from /var/www/massivecoupon to the real path of the massivecoupon folder itself, and then modify the permission of that folder to the proper user for rwx.
• For any absence of modules you can try searching on this website: http://pypi.python.org/pypi/
