Tests fail without ctypes on Python 2.4

Output is as follows:

Error while importing gis:  File "./runtests.py", line 130, in django_tests
    mod = load_app(model_label)
  File "/usr/lib/python2.4/site-packages/django/db/models/loading.py", line 72, in load_app
    mod = __import__(app_name, {}, {}, ['models'])

Tested on r8287, Debian Etch, Python 2.4.4

I notice you changed the summary to specify Python 2.4. The Python community buildbot running the current Python 2.6 trunk is also seeing a similar failure, this is from the stdio output here: ​http://www.python.org/dev/buildbot/community/all/?show=sparc%20Solaris%2010%20trunk

Actually now that I look at that cloesely I see it is slightly different. Feedback on what's going on here, if you have any idea, would be appreciated. This does not happen on my test machines running Python 2.6 beta2 so I'm not sure what the difference is and had not started to dig into it at all since I (mistakenly?) thought it would be covered by this ticket.

(In [8289]) gis: Fixed #8207; now shield 2.4 test runners from attempting to import ctypes.

The fix in 8289 should also apply for the Python 2.6 problem. It looks to me like ctypes isn't installed properly with 2.6. Specifically, it can't find _ctypes, which has C implementations for the ctypes API. This implies it wasn't compiled with or is missing from the 2.6 distribution you're using.

OK, I'll forward that info to the buildbot owner. Thanks.
