1. emacs can't build emacs.git's snapshot for some reason
2. I think let guile-emacs inherit emacs-snapshot or emacs-next is more reasonable, for  guile-emacs is a kind of emacs-next.

By the way, when I use the below command:
 
   guix build emacs-snapshot --with-source=./emacs-snapshot-20151111.tar.gz

to build a new emacs-snapshot, How can i install it?  I can't find any help on manual....

At the momenti, i only use guix as a tool to build emacs-snapshot. but I find it is not easy use as evm, i have to switch back evm.
