GAE: remote_api_shell.py uses wrong Django version

I have a Python 2.7 GAE app that uses Django 1.2. Everything generally works fine.

I'm trying to use remote_api_shell.py, but when I import my models.py, I get this error:

$ PYTHONPATH=.; remote_api_shell.py APP
App Engine remote_api shell
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]
The db, users, urlfetch, and memcache modules are imported.
s~APP> import models
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Users/.../models.py", line 8, in <module>
    from django.core.validators import email_re
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/django_0_96/django/core/validators.py", line 13, in <module>
    from django.utils.translation import gettext, gettext_lazy, ngettext
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/django_0_96/django/utils/translation/__init__.py", line 3, in <module>
    if settings.USE_I18N:
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/django_0_96/django/conf/__init__.py", line 28, in __getattr__
    self._import_settings()
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/django_0_96/django/conf/__init__.py", line 53, in _import_settings
    raise EnvironmentError, "Environment variable %s is undefined." % ENVIRONMENT_VARIABLE
EnvironmentError: Environment variable DJANGO_SETTINGS_MODULE is undefined.

I don't know why it is using Django 0.96 here. Especially since I think Python 2.7 supports only Django 1.2. Here are the relevant parts of my app.yaml:

application: APP
version: prod
runtime: python27
api_version: 1
threadsafe: true

[...]

libraries:
- name: django
  version: "1.2"

If I comment out the from django.core.validators import email_re line then the import succeeds.

Any idea if I am doing something wrong or if this is this a GAE bug?

FYI this no longer works because 

use_library('django', '1.5')

now throws this error:

ValueError: 1.5 is not a supported version for django; supported versions are ['0.96', '1.0', '1.1', '1.2', '1.3']

Hopefully this is a temporary problem, but my solution was to delete (rename):

C:\Program Files (x86)\Google\google_appengine\lib\django-0.96

to something else, then the proper version of django loads w/o any other problems.

I had the same issue, and I solved it by running these two lines once I open the remote API session:

from google.appengine.dist import use_library
use_library('django', '1.3')

Though, clearly, it's a hack. Star this issue to encourage the app engine team to fix it:

try typing this:

import django
django.VERSION

To check the django version! I am guessing that the python console that u are running has the old version of django!
