Checking for GTK version ...
Error: The GUI requires GTK devel packages (which were not found).

Check "configure.log" if you do not understand why it failed.

how can I install that one ?
The GTK-2 dev package is called libgtk2.0-dev I believe. So running "sudo apt-get install libgtk2.0-dev should install it.
