Cannot find pkg-package 'sox'

Created by: siebenkopf

When I build the package, I get the error that

RuntimeError: pkg-config package `sox' was not found

I tried to install thesox package using

sudo apt-get install sox

which succeeded, but the error remains. Which is the correct package to install to get sox running? Should we add that to the installation instructions of this package, or even to the global Bob installation instructions?
