I have Pythong2.6, psycopg2 and pgAdmin3 installed using Macports. My settings.py is:
DATABASE_ENGINE = 'postgresql_psycopg2' # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
DATABASE_NAME = 'mysite' # Or path to database file if using sqlite3.
DATABASE_USER = 'postgres' # Not used with sqlite3.
DATABASE_PASSWORD = '' # Not used with sqlite3.
DATABASE_HOST = '' # Set to empty string for localhost. Not used with sqlite3.
DATABASE_PORT = '' # Set to empty string for default. Not used with sqlite3.
The error I get when I run python manage.py syncdb is:
Traceback (most recent call last):

Please note, I am a complete beginner in this stuff. I am originally a PHP-guy and trying out Python for a small personal project. Do I need to "turn on" Postgres?
Also, when I sudo python manage.py runserver 8080 I get this error:

Please guide me. Any reply will be appreciated.

There seems to be a problem with your psycopg2
installation – Python does not find it. This is a Python installation problem, not a Django issue.
You can try to load it manually using the Python interpreter and see if it works:
$ python
>>> import psycopg2
If you get an ImportError
exception, your installation is erroneous. To get a list of all directories Python looks for modules, use sys.path
:
$ python
>>> import sys
>>> print sys.path
You can also add custom directories to Python's module search path by modifying the sys.path
variable. Do this somewhere before the respective import
statement(s):
import sys
sys.path.append("my-path")
# ...
import psycopg2
