It's wrong that you assume every widget has proper implementation
for every possible arg you think of:-)
GtkClock doesn't have a "type" GtkArg, so it's impossible for the
perl module to set the "type" arg of a GtkClock object.
Just build the widget with:

$clock = new Gtk::Clock('realtime');

You cannot change the type later from perl because you cannot change
it from C either (with the published interface, at least).

My bad: I modified the GtkLayout in Gtk, but it gets built the one in 
Gnome. I'll change this soon (along with GtkSocket/Plug, I guess).

I wonder how Gtk::Pixmap->set_build_insensitive('0') ever worked since
it's not bound in any version of the module I know of (and also
according to the cvs logs).
Here again "build_insensitive" is not an arg for Gtk::Pixmap.

I think the args for the widget types are documented in the RDP
manuals for gtk+: you may want to check them.

There is another issue here anyway: the GtkPixmap api is broken
when used in a OO language like perl, because it uses the same
method name of a parent class (gtk_object_set()). In this case
you may need to use something like:

$pixmap->Gtk::Object::set("argname", $argval); # ugh!
