Have you considered that these instructions could be faulty or out-of- 
date?
Does the file you're looking at carry a date?

I found some rather old (Emacs 20!) cua.el files out there just now.

C-h v over the variable in question doesn't give anything, i.e. it's  
not a known variable... that is usually a good indicator that the  
names have changed.

If you have C-h v cua- TAB, you get a bunch of variable names that  
have to do with cua.  One of them is `cua-overwrite-cursor- 
color' (note the capitalization), which I think is what you're  
interested in.
