did you try installing them? If not, update python, then install them. If you tried installing them, get a fresh copy of blender and install the exporters after updating python.

Use blender, sketchup is designed for architectural design only.
Just do what they said, export to blender, add armetures, export to .dts. I made a tutorial:First, make your model:Then, export it to .dae:Download Blender:http://www.blender.org/download/get-blender/Download the .dae to blender importer: http://sourceforge.net/projects/colladablender/files/Then, follow this tutorial:http://forum.blockland.us/index.php?topic=66763.0When you are ready to script, follow the scripting portion of this tutorial:http://forum.blockland.us/index.php?topic=78760.0
