I am trying to get TK::Progress bar going for a project I am working on. This code runs fine under Win32 but hoses with no errors under Linux which is where I need this to run. When executed it waits a few secs then just returns the command prompt. 
#!/usr/bin/perl

use Tk;
use Tk::ProgressBar;

my $mw = MainWindow->new(-title => 'Processing');

$Progress = $mw->ProgressBar(
        -width => 30,
        -from => 0,
        -to => 100,
        -blocks => 50,
        -colors => [0, 'green', 50, 'yellow' ,80, 'red'],
        -variable => \$percent_done
   )->pack(-fill => 'x');

 $mw->Button(-text => 'Go!', -command=> sub {
    for ($i =0; $i < 1000; $i++) {
     $percent_done = $i/10;
     print "$i\n";
     $mw->update; 
   }
})->pack(-side => 'bottom');

Mainloop;

I intially thought that maybe the mod was not installed correctly but I checked and it was fine. I am pretty sure it is in the Tk standard library. Anyways it shows as being up to date:

CPAN Terminal>m Tk::ProgressBar
0001 Tk::ProgressBar 1.04 ACH
CPAN Terminal>install 0001
Installing: Tk::ProgressBar
Module Tk::ProgressBar already up to date; won't install
without force!
All cached data has been flushed.

any help would be appreciated!

cheers!
