ogr2ogr OUTPUTLAYER.shp strade.shp -dialect sqlite -sql "SELECT 
ST_Line_Interpolate_Point( geometry , 0.5 ),* FROM 'strade'"
ERROR 1: In ExecuteSQL(): sqlite3_prepare(SELECT 
ST_Line_Interpolate_Point( geometry , 0.5 ),* FROM 'strade'):
   no such function: ST_Line_Interpolate_Point

I have both SQLite and SpatiaLite support on. What's going on?
