Keep in mind that the Glib library needs to be compiled and you should be very careful when replacing an older version. Comprehensive compiling instructions can be found on the Gnome website or inside the achive.
Also, GLib depends on a number of other libraries and it support a large variety of extra configuration options, such as --enable-debug, --disable-gc-friendly and --enable-gc-friendly.
