libglib-perl 3:1.329.3-3 (s390x binary) in ubuntu mantic

 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/>).
