I've put here one adaptation for "no-beamer" documents of this code. Thanks a lot for the indications given below by Daniel.

The \btIfInRange macro depends on the pgffor package. Just add it to the list of packages you load and the code compiles just fine.

Note that the implementation you use has the drawback that all nonselected lines also get a background color (which is white in your case, so you do not really see it). However, as soon as you put a listing in some \colorbox or choose another color for the main font, the result may look ugly. In my answer to the Highlighting line ranges in a lstlisting: partial solution, but expansion issues I have presented a workaround that overcomes this limitation.
