GDAL 1.5.0-1

GDAL 1.5.0-1 release is here. And, with some surgery I was able to get Xerces built 64bits (Xerces is used for the GML format). I also decided that Xerces was of limited scope (just GDAL), so it is built into GDAL and I won’t update the Xerces framework for Leopard. This also simplifies the installation of GDAL.
