Import .stl in blender Game Engine and GE script error

Hi
I need to create an import-function for Game Engine to import .stl or other similar 3D volumetric directly in Game Engine (without passing trough Blender environment).
I used batch_stl.py in GE with Blender 2.4.9 and I receveid this error:

Python script error from controller “Import_stl.py#CONTR#1”:
Traceback (most recent call last):
File “Import_stl.py”, line 52, in <module>
ImportError: No module named Blender
Python script error from controller “Import_stl.py#CONTR#1”:
Traceback (most recent call last):
File “Import_stl.py”, line 52, in <module>
ImportError: No module named Blender

Thanks a lot for any suggest.
