Cannot successfully create field '...' for model '...': name '...' is not defined

[equalium]

Hello, i've just installed trunk version.
I'm trying to migrate an existing app, the 0001_initial.py is created,
but trying to fake it, i get:

Cannot successfully create field 'distribuidor' for model 'equipo':
name 'Distribuidor' is not defined.

I have edited 0001_initial.py adding:

from distribuidores.models import Empresa as Distribuidor

as model 'equipo' uses

equipos.equipo': {
...,
'distribuidor': ('models.ForeignKey', ['Distribuidor'],
{'null': 'True', 'blank': 'True'}),
...

'Distribuidor' is the imported name of the model 'empresa' from
another app.

But still get the same error.
This is the full sequence of the error:

./manage.py migrate equipos --fake
0001_initial
While loading migration 'equipos.0001_initial':

Maybe this is not enough info to figure what's going on, but if
anybody has any idea of what can be wrong I'd appreciate any hint.

note: I am using south in a virtualenv.

Thank you.

I think this may well be a bug (specifically, bug #134). Now you've
provided a traceback, I can hopefully get it fixed; keep an eye on
http://south.aeracode.org/ticket/134
