Hi List,

I am learning gtk-perl  programing. To under the programming language. 
I have copied and pasted a program from the tutorial. I get the following error. 
My distribution is FC7. 

I am running the program typing Perl and name of the program at the console. Can someone guide as to what is missing in the above.

#
# rm

use strict;
use Gtk2 '-init';

my $window = Gtk2::Window->new;
my $label = Gtk2::Label->new ('Hello World!');
$window->add ($label);
$window->show_all;
Gtk2->main;
