Greetings!
This is the author of said website. I've just put up a post re: this issue. I made a script that will set up the SciTE, Stella, DASM setup I'm using on my Win 7 machine on an Ubuntu setup. It may work for other Linux installs.
Anyway, the post is here. It will download and install everything for you. Just launch it as follows:
sudo script-filename $USER
Cheers,
