"Can't exec '/usr/bin/make'"... when compiling a framework project

I am trying to compile a framework (that came as a project folder). When I click Build, I get this:

error: can't exec '/usr/bin/make' (No such file or directory)

... and sure enough it's not there. How do I resolve this? I am using XCode 4.3.2

You may need to [install the command-line tools][1] from inside Xcode.

If that doesn't fix it, also try doing this in a Terminal:

sudo xcode-select -switch /Applications/Xcode.app
