Reduced the code down to:
#########################################
use Tkx;
     Tkx::package_require("Tktable");
 	my $b = $mw->new_button(
        -text => "Exit",
        -command => sub { 
		$mw->g_destroy; 
		}
    );
    $b->g_pack;
	
    Tkx::MainLoop();
#########################################

Still get error on exit;

Comment out this:

#########################################
# Tkx::package_require("Tktable");
#########################################

And errors goes away.
