./configure --with-topology --with-raster && make && make check &&
sudo make install

 createdb pgis20_tests
 createlang pgis20_tests plpgsql
 psql -f postgis/postgis.sql pgis20_tests

Then you have your old databases using 1.5.3 and the new database
using 2.0.0SVN.

Don't miss to also install GEOS-3.3.1 for getting most out of topology
(install it _before_ building the new postgis).
