OgreXMLConverter script problem

I’m using Slackware 11 with blender 2.42a download from linuxpackages.net. I am trying to use the OgreXMLConverter to convert a .blend file to a .mesh that the ogre3d library can handle. I downloaded the .tar.gz file for the converter from http://www.ogre3d.org/wiki/index.php/Tools:_Blender#OGRE_Meshes_Exporter
I put everything in the .tar.gz file in the .blender/scripts in my home directory. I then loaded blender and went to the script window. I then hit update menu and it appeared in the export menu. When I try to run this script the console recieves this error message:
Traceback (most recent call last):
File “<string>”, line 1, in ?
ImportError: No module named BPyRegistry
Where do I find this script? Thanks.

maybe here?
