that is because the object matrix (mathematic thing used to rotate/scale/move the whole object) is not regarded in the current export.
we should update the version, my one at home is already fixed with it...
you can work around it by reseting all transformations:
"apply scale/rotation"
this is a menue-entry in (object?)mode. After this the exporter should export like yu see the mesh in blender. (for Glest the must lie on the ground, you can see it if you import other models).
