Sorry, should have said:

This is with ghc 6.2.1, same problem with my 6.3 cvs from about a month
ago.

If you want to run this program you need to link with a few things:

ghc -ffi -O --make Test.hs -o test '-#include <glib-object.h>'
-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -lgobject-2.0
-lglib-2.0

This is on Linux with glib-2.0 installed (it's part of gtk/gnome).
