I get an error:

~ $ sudo apt-get install build-dep xfce4-screensaver
[sudo] password for m:       
Reading package lists... Done

E: Unable to locate package build-dep

The man page tells me the syntax is actually apt-get build-dep [pkg],
not apt-get install build-dep [pkg]. That gets me to here:

~ $ sudo apt-get build-dep xfce4-screensaver
Reading package lists... Done
E: You must put some 'deb-src' URIs in your sources.list
