Ran the !GeoDjango test suite on Oracle 11g and received the following
errors:
{{{
======================================================================
FAIL: Testing GML output from the database using GeoManager.gml().

The first failure is simply different precision values in the GML output,
and is easily solved with a better regex in the test suite. The next two
problems from the distance test suite, however, will require more
investigative work.
