If you just want the binary you can simply use checkinstall:
This will add a ffmpeg2 package to your package management system. It may still cause issues for packages that directly use the ffmpeg binary supplied by the so-called "ffmpeg" package.
sudo checkinstall --pkgname=ffmpeg2 --pkgversion="2.0" --default --backup=no install -Dm755 ~/bin/ffmpeg /usr/local/bin/ffmpeg
Another method is to move the files wherever you want and add the directory to your path: How to add a directory to my path?
Note that the guide you linked to will install the most recent ffmpeg code, and not necessarily a particular release. This is just fine for normal users since the releases are generally used by distros.
