I found this: http://trac.osgeo.org/gdal/ticket/2271. Apparently,
automatic projection is integrated into the ogr KML driver. It seems
that this feature was introduced with GDAL 1.6, so if you have an
earlier version you have to reproject first. So, I think we shouldn't
introduce a fatal error, but maybe just a warning in the man page.
