Hi

I am trying to compile the ghello.c file from mission 1 on ubuntu 11.04.
I have installed
$sudo apt-get install libgtk-3-dev

and am trying to compile with
$gcc -Wall ghello.c -o ghello `pkg-config --cflags gtk+-3.0` `pkg-config --libs gtk+-3.0`

which compiles fine, but when I try to run it, I get the error

$Gtk-Message: Failed to load module "canberra-gtk-module"

but when I try to install canberra, its already there

$libcanberra-gtk-module is already the newest version.

how can I run this program ?
