Problem following Tk demo in Advanced Perl Programming

[elbie]

I feel really stupid asking this. My apologies in advance.

I'm working through the Perl/Tk chapters in O'Reilly's Advanced Perl Programming. I typed in the menu example verbatum minus comments and with only one button (included below) and I get this error:

No -label at /usr/lib/perl5/site_perl/5.005/i586-linux/Tk/Widget.pm line 247

The perldocs for Tk::Menubutton, Tk::options, Tk::Menu, and Tk::Widget don't make any reference to a label option in any way that I can find meaningful.

Is there some other distro of Perl/Tk that I should be using? How can I tell?

use Tk;
$top = MainWindow->new();
$menu_bar = $top->Frame()->pack(side => 'top');
$search_mb = $menu_bar->Menubutton(text => 'Search',
                   relief => 'raised',
                   borderwidth => 2
                   )->pack(side => 'left',
                       padx => 2
                       );
$search_mb->command(label => 'Find',
            accelerator => 'Meta+F',
            underline => 0,
            command => sub {print "find\n"}
            );
