The Great Bridge installer should be fine. I haven't played with it
myself. It's just a GUI front end that executes the various install
steps for you, the actual install process isn't any different than a
normal install. I believe it installs from source because it is
supposed to work on all platforms.
Our documentation was written before the Great Bridge installer was
released. If you (or someone else) goes through an install and wants
to submit changes to our install docs, go for it.
