libglib1.2 1.2.10-10.1build1 (amd64 binary) in ubuntu dapper

 GLib is a library containing many useful C routines for things such
 as trees, hashes, and lists. GLib was previously distributed with
 the GTK+ toolkit, but has been split off as of the developers' version
 1.1.0.
 .
 You do not need to install this package if you have libgtk1 (note 1,
 not 1.1 or 1.2) installed. libgtk1 included libglib in it. libgtk1.1
 and libgtk1.2, however, do need libglib1.1 to be installed separately.
