This is probably your problem. Develop on a VM in linux, or install
manually by source on a Mac -- do '''NOT''' use homebrew. It causes a
significant amount of frustration on my part because it can use wrong
linker flags, use incompatible libraries, and in general causes crazy
issues such as this.
Regardless, I tried the following query using models from !GeoDjango's
test suite (which mimics the example you did, two models with
`PointFields` that have `srid=4326`):
{{{
#!python
>>> from django.contrib.gis.tests.geoapp.models import City
>>> from django.contrib.gis.tests.distapp.models import AustraliaCity
>>> qs =
City.objects.distance(AustraliaCity.objects.get(name='Thirroul').point)
>>> c = qs[4]
>>> print c.name, c.distance
Pueblo 8342.02642135
}}}
Thus, I cannot reproduce -- I'm using PostGIS 1.5.5. Please provide a
concrete test case that demonstrates this to reopen.
