Incompatible with MySQL databases?

[mjray]

After installing django-fortune and adding it to INSTALLED_APPS, the following error appears:

$ python manage.py fortune    
SystemCheckError: System check identified some issues:                                              

ERRORS:
fortune.Pack.name: (mysql.E001) MySQL does not allow unique CharFields to have a max_length > 255.  

Expected behaviour was to display a grumble about lack of fortune packs loaded, as shown in the README.
