10.10 - Compiling latest GNOME-Shell

This question pretends to be a central place where people share info about compiling the latest and greatest GNOME-Shell environment in Ubuntu 10.10.

As GNOME-Shell now depends on gtk3 and in a lot of other new modules, and the GNOME-hell PPA is no longer around, it's actually quite difficult to test it without, as I've read somewhere,

"compiling half of the GNOME desktop"

I've tried with jhbuild just yesterday and only some modules were built, but gnome-shell and gtk3 weren't included in those that built.

As some solutions posted here may seem get quite dangerous, I was thinking about setting up a VM w/ Ubuntu 10.10, and I think that most of you will agree with me.

So, in conclusion, questions that need to be answered:

1. Is there any new GNOME-Shell PPA for
   Maverick?



2. Can jhbuild gnome-shell install script be fixed in order to allow a clean build?




3. If not, any other easy ways to get it, excluding manual compilling?




4. When installed, will GNOME-Shell work with Virtualbox emulated graphics stack?

Ladies and gentleman, the question is now yours. Let the answering begin...
