Knoppix is based on debian, so you can try my repository for install (see signature).
You have to install it (and knoppix also I think, but I'm not sure) to a hdd of course, or you have to reinstall it everytime you start the Live CD.
Don't forget to install the appropriate wxWidgets packages too.
If you put apt.wxwidgets.org to your package sources list, the dependencies are fullfilled automatically.
