You probably don't want to hear this, but i see text just fine, with  
absolute silence on stderr.  Works with both of

Gtk2
  $Gtk2::VERSION = 1.080
  Compiled for gtk+ 2.4.0
  Running with gtk+ 2.4.14
Gnome2::Canvas
  $Gnome2::Canvas::VERSION = 1.002
  Compiled for 2.6.0

and

Gtk2
  $Gtk2::VERSION = 1.111
  Compiled for gtk+ 2.8.2
  Running with gtk+ 2.9.0
Gnome2::Canvas
  $Gnome2::Canvas::VERSION = 1.002
  Compiled for 2.13.0

In some newer operating systems, time_t has been widened to 64 bits.  
In the negative direction, this goes back more than twenty times the  
age of the universe, and so suffices. In the positive direction,  
whether this range is sufficient to represent all possible times  
depends on the ultimate fate of the universe, but it can be expected  
to postpone overflow long enough for such implementation limits to be  
abolished.
