After gluing your busted pieces together (don't use the Gorilla Glue for this - it expands as it dries), cut a piece of mesh tape to bridge the repaired area, stick it in place, then apply a liberal coating of the Gorilla glue. It'll be an amber color at the outset, but will become whiter as it dries and turns into a sort of semi-hardened resin. Since GG is designed to cure in the presence of moisture, giving the repaired area a quick shot over a humidifier helps the process along. After it dries, you can repeat the process with as many layers of tape and/or glue as you feel necessary. Here's a photo of how the repair appears right after application of the glue:

And here's how it looks once cured:
