Can't find GDAL data files (``GDAL_DATA``)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When installed from source, GDAL versions 1.5.1 and below have an autoconf bug

like this:

The solution is to set the ``GDAL_DATA`` environment variable to the location of the
GDAL data files before invoking Python (typically ``/usr/local/share``; use
``gdal-config --datadir`` to find out). For example::
$ export GDAL_DATA=`gdal-config --datadir`
$ python manage.py shell
If using Apache, you may need to add this environment variable to your configuration
