ImportError: No module named mysql.base, in django project on Ubuntu 11.04 server

问题

I am following the steps in the Django Book and got to the part where the authors explain hot wo set up a django project to use a database. I chose mysql.

My settings in settings.py are:

DATABASES = {
    'default': {
        'ENGINE': 'mysql',               # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'mydatabase',                  # Or path to database file if using sqlite3.
        'USER': 'myname',                # Not used with sqlite3.
        'PASSWORD': 'mypassword',        # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

When trying to start the server, the following message is printed:

Validating models...

ImportError: No module named mysql.base

I googled a little and found out, that this message could be printed if you use an older version of MySQLd. So I made sure I got the latest version. And tested the import in an interactive python shell. It's fine.

Any other suggestions, why this doesn't work?

I am working on a fresh installed Ubuntu 11.04 Version (Wubi in Windows 7), if that matters. =)
