I am referring to the "Compiling Audacity Step by Step Guide" AKA
"Compiling Audacity for Beginners".

The purpose of that page seems self evident to me - it is to provide a
simple step-by-step guide to compiling Audacity for beginners.
We currently have over a thousand words on that page about how to
install WxWidgets. Surely for the purposes of that page it is more
appropriate to just say something like:

"Step ...) sudo apt-get build-dep audacity (enter password when prompted)"
