Jeppe,

This error message comes from the OGR ODBC driver when it
asks the lower level CPL ODBC code for the column name "WKT"
and it is not found.  This likely means that for some reason
the newer ODBC code in gdal/port is not recognising this as a
valid or understandable column for some reason.

Could you download FWTools and try it to see what an ogrinfo report
for the layer shows?

When built with geos and ogr, mapserver will use the geos wkt translation
in preference to the ogr wkt translation.  But I'm not sure why this isn't
working.  The WKT geometry looks valid to me.
