I was following Newcomers guide on GNOME's wiki. Everything was good up to running below command on guide
$ jhbuild build adwaita-icon-theme dconf glib-networking gvfs libcanberra
On terminal it gives following output (just error part):
Makefile:464: recipe for target 'dconf-dconf-update.o' failed
make[2]: *** [dconf-dconf-update.o] Error 1
make[2]: Leaving directory '/home/mkykadir/.cache/jhbuild/build/dconf/bin'
Makefile:387: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1

Which operation to follow, I tried 1, 4 and 6 options and they didn't change the situation. I am using Ubuntu GNOME on a dual core machine.
