Comment:
I have now an updated patch in
https://github.com/akaariai/django/tree/postgis2. This needs another
review.
I do get errors from the test suite:

The failures seem to be about float conversion. On my laptop I got
different errors, again related to float rounding. The question is if this
is related to the updated PostGIS & dependencies, or if it is a pre-
existing failure. At least on the laptop these errors seem to be present
even using PostGIS 1.5.
