Gnome-Shell building fails on Arch Linux

[Alessandro Crismani <alessandro crismani gmail com>]

Hi everybody,

I'm using Arch Linux and I would like to build a bleeding edge snapshot 
of gnome-shell, however jhbuild fail at step 3 with the following error:

./json-parser.c:916:38: error: comparison between ‘GTokenType’ and ‘enum 
<anonymous>’

If I continue the build process it ends saying success, however when I 
launch ./gnome-shell --replace I get something like GConf schemas 
missing, killing the shell.

Besides, I tried to compile on Fedora and it works like a charm, am I 
missing some dependency which I am not aware of?

I tried the Arch AUR package and it works fine (now I have the GConf 
schemas thanks to it, so I can't reproduce the previous error), however 
I would like to be able to compile the lastest source.

I searched through Google but I can't find anything related to my 
problem, is anybody able to help me?

Thanks in advance, and keep up with the project!

Cheers,
Alessandro
