We're currently in the process of figuring this out as well. While we haven't done so properly, we do have a rather annoyingly ugly hack to get around it.

We simply define a "dummy" function somewhere in the code (for example your models.py or even settings.py) and fill it up with all the strings that we need to have a translation for.

from django.utils.translation import ugettext_lazy as _, pgettext

def dummy_for_makemessages():
    """
    This function allows manage makemessages to find the forecast types for translation.
    Removing this code causes makemessages to comment out those PO entries, so don't do that
    unless you find a better way to do this
    """
    pgettext('forecast type', 'some string')
    pgettext('forecast type', 'some other string')
    pgettext('forecast type', 'yet another string')
    pgettext('forecast type', 'etc')
    pgettext('forecast type', 'etc again')
    pgettext('forecast type', 'and again and again')

This function is never called but simply defining it prevents the message strings from getting commented out by makemessages.

Not the most elegant solution but it works.
