You just need to use -exportselection=>0; A simple example 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;

my $mw = MainWindow->new();
my $f = $mw->Frame(-border => 1)
        ->pack(-side => "left", -fill => "both");

my $envs_list;
$envs_list = $f->Scrolled("Listbox", -scrollbars=>"e", 
                 -exportselection => 0, 
         -selectmode=>"extended")->pack(-fill => 'both');
$envs_list->insert("end", "abcda");
$envs_list->insert("end", "abcdb");
$envs_list->insert("end", "abcdc");
$envs_list->insert("end", "abcdd");

my $list;
$list = $f->Scrolled("Listbox", -scrollbars=>"e", 
                -exportselection => 0, 
        -selectmode=>"extended")->pack(-fill => 'both');
$list->insert("end", "abcd1");
$list->insert("end", "abcd2");
$list->insert("end", "abcd3");
$list->insert("end", "abcd4");
$list->insert("end", "abcd5");

$mw->Button( -text => "Selections", -command =>
  sub{ 
    my $selected_env_list = 
      $envs_list->get( $envs_list->curselection );
   my $selected_list = 
      $list->get( $list->curselection );
    print "selected-> $selected_env_list  $selected_list\n";
          } )->pack( -side => 'left' );

$mw->Button( -text => "Exit", -command => \&exit )->pack;

MainLoop;
