While trying to build clutter from JHBuild, I get stuck at the stage where I have to clone it:
$ jhbuild buildone clutter
*** Checking out clutter *** [1/1]
git clone http://git.clutter-project.org/clutter
Cloning into clutter...
It just chills there, and it seems nothing is happening at all. When I check the bandwidth usage, there's hardly anything.
update 1: Well, I wonder what happened, but it works now. Probably slow network on my (or their) side.
update 2: One of JHBuild developers (on IRC):
git.clutter-project.org is unreliable; it will soon be moved to git.gnome.org, afaik.
