schemamigration auto not working

[pcg92]

 ! Cannot freeze field 'website.x.url'
 ! (this field has class url_or_relative_url_field.fields.URLOrRelativeURLField)

 ! South cannot introspect some fields; this is probably because they are custom
 ! fields. If they worked in 0.6 or below, this is because we have removed the
 ! models parser (it often broke things).
 ! To fix this, read http://south.aeracode.org/wiki/MyFieldsDontWork

It's not going to support South, sorry.
