What steps will reproduce the problem?
1. Place python script file in blender's scripts folder
2. Open Blender
3. Select to export as webGL native anywhere
4. Click export file
5. Error message that a python script error will appear

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

I also had to copy the bpy_io lib across from 2.58a

Perhaps this is a linux issue only?
Here (Ubuntu 10.04 64bit, Blender 2.58a) some python imports live in a 
different folder.

e.g. io_utils lived in "modules", now it lives in "modules/bpy_extras"
therefore import lines must be adjusted from "io_utils" to 
"bpy_extras.io_utils".
(same with other imports?!)

-> Don't know if this will persist.

Maybe it's a linux only thing... i'm actively maintaining another exporter 
which is only based around JSON (and my Binary JSON format) at 
http://code.google.com/p/blender-machete/ maybe that could help... give it a 
shot and tell me how it works
