gnome-shell deps

Hi,

I've now successfully build gnome-shell (from gnome overlay)

But now, it doesn't run at all

I think it needs some other package but which ?

What should be built and started for gnome-shell starting ?
Have I to build all the gnome-2.32 packages ?

Here is the last output:

#gnome-shell --replace
