Building Gnome, missing dependency?

Question

I'm trying to follow the instructions in http://live.gnome.org/GnomeShell#building to build gnome, for learning, on my arch linux box.
Ok, as usual, I'm stuck in the first steps... Which means I suck. That aside, can I get any help?
$ sh gnome-shell-build-setup.sh Updating jhbuild ... done
Installing jhbuild ... done
Writing ~/.jhbuildrc ... done
Installing modules as system packages when possible
System installed packages which are new enough:
## BUNCH OF PACKAGES HERE
System installed packages which are too old:
telepathy-glib (required=0.17.5, installed=0.16.4)
mozjs185 (required=1.0.0, installed=)
webkitgtk-3.0 (required=1.7.90, installed=1.6.3)
libcroco-0.6 (required=0.6.4, installed=0.6.3)
libxklavier (required=5.2.1, installed=5.1)
No matching system package installed:
libnl-3 (required=3.2.7)
However:
$ pacman -Qs libnl
local/libnl 3.2.7-1
Library for applications dealing with netlink sockets
And it IS installed!
Help?

it's fine. the script uses pkg-config and the file is libnl-3.pc
/usr/lib/pkgconfig/libnl-3.0.pc
your lest problem is libnl.

you want to takle this ones first
yeah, I've spent a while trying to create a PKGBUILD for telepathy-glib, and then after upgrading it the script will add it to the "no matching system package installed" list. So it isn't properly detecting arch linux packages.
Also, of course after upgrading latest telepathy-glib gnome 3.2 won't work. I'll create a VM for this purpose and try to work the script so that it properly functions with arch linux.
Thanks for everybody's opinions.
