I have posted this already into Seekers of Perl Wisdom, but I think perhaps its of more general interest
i have a little problem : i have the following lines of code (that work fine under linux): 
sub select_dir{
    my $choose_dir = $main->Toplevel;
    $choose_dir->title("Choose directory:");
    my $ok = 0;
    my $frame = $choose_dir->Frame->pack(
                 -fill => "x",
                 -side => "bottom"
        );

    my $curr_dir = Cwd::cwd();

    my $scrolled;

    $scrolled = $choose_dir->Scrolled('DirTree',
              -scrollbars => 'osoe',
              -width => 35,
              -height => 20,
              -selectmode => 'browse',
              -exportselection => 1,
              -browsecmd => sub { 
                               $curr_dir=shift },
              -command   => sub { $ok = 1 },
                    )->pack(-fill => "both", -expand => 1);

    $scrolled->chdir($curr_dir);

    $frame->Button(-text => 'Ok',
           -command => sub { 
                      $ok =  1 }
                )->pack(-side => 'left');
    $frame->Button(-text => 'Cancel',
           -command => sub { 
                      $ok = -1 }
                )->pack(-side => 'left');

    $frame->waitVariable(\$ok);
    $status->configure(-text=>"Status area");
    if ($ok == 1){
        $choose_dir->withdraw;
        if (-x $curr_dir){
            return $curr_dir;
        }
        tackle_err ("$1 doesn't exist");
        return;
    }
    else
    {
        $choose_dir->withdraw;
        return;
    }

}
