libglib-perl 2:1.241-1 (amd64 binary) in ubuntu quantal

 Glib provides a Perl interface to the GLib and GObject libraries, as part
 of gtk2-perl. It attempts to provide a perlish interface while remaining as
 true as possible to the underlying C API, so perusing the reference manual is
 recommended (see <URL:http://developer.gnome.org/doc/API/2.0/glib/>).
