gtk+ uses pango for all of its text rendering -- this is at the C 
level, and there's nothing the bindings can do about that.

if you fail to call gtk_init() (or Gtk2->init) in your program, the 
error messages often come from pango instead of something more 
elucidating.  of course, there's a call to init right there on line 27, 
so that's not it, but i think pango often gets blamed for things that 
are not its fault.

like ross says, this sounds like a broken installation.  did you 
install Glib and Gtk2 from source?  if so, did they pass their test 
suites?  in any case, can you run the gtk-demo program?  (don't know 
if/where it gets installed on your system, but in the source dist it's 
Gtk2/gtk-demo/main.pl)

the easiest way, Gtk2::Button->new_from_stock ($stock_id), will still 
give you text on the buttons, so that's not going to help.  you'll have 
to change each button creation from

  my $prevbut = Gtk2::Button->new ("Previous Pic");
  my $nextbut = Gtk2::Button->new ("Next Pic");
  ...

to something like

  my $image;
  my $prevbut = Gtk2::Button->new;
  $image = Gtk2::Image->new_from_stock ('gtk-go-back');
  $prevbut->add ($image);
  my $nextbut = Gtk2::Button->new;
  $image = Gtk2::Image->new_from_stock ('gtk-go-forward');
  $nextbut->add ($image);
  ,,,

the stock items (and their string names) are listed at 
http://developer.gnome.org/doc/API/2.0/gtk/gtk-Stock-Items.html  ...

you wouldn't want to.
