Gracias Felipe por tu respuesta!

Estuve googleando un poco y encontre esto:

" The form field's label is set to the verbose_name of the model field,
with the first character capitalized. "

Así que modifique mis modelos:

from django.db import models
from django.utils.translation import ugettext_lazy as _

#===============================================================================
# Province model
#===============================================================================
class Province(models.Model):
    name = models.CharField(verbose_name=_('name'), max_length=30)

    class Meta:
        verbose_name = _('province')
        verbose_name_plural = _('provinces')

    def __unicode__(self):
        return u'%s' % (self.name)
#------------------------------------------------------------------------------

El tema es que por mas ponga _('name') o _('province') el resultado sigue
siendo el mismo. Vos a que te referis con cambiar o referenciar al label
del campo?

Saludos!
