-If you are on Python 2.6, you will also have to compile pysqlite2, because
-``SpatiaLite`` must be loaded as an external extension, and the required
-``enable_load_extension`` method is only available in versions 2.5+ of
-pysqlite2. Thus, download pysqlite2 2.6, and untar::
-
-    $ wget http://pysqlite.googlecode.com/files/pysqlite-2.6.3.tar.gz
-    $ tar xzf pysqlite-2.6.3.tar.gz
-    $ cd pysqlite-2.6.3

-Next, use a text editor (e.g., ``emacs`` or ``vi``) to edit the ``setup.cfg`` file

-    libraries=sqlite3
-    #define=SQLITE_OMIT_LOAD_EXTENSION
-
-.. note::
-
-    The important thing here is to make sure you comment out the
-    ``define=SQLITE_OMIT_LOAD_EXTENSION`` flag and that the ``include_dirs``
-    and ``library_dirs`` settings are uncommented and set to the appropriate
-    path if the SQLite header files and libraries are not in ``/usr/include``
-    and ``/usr/lib``, respectively.
