Comment 3 for bug 916477

What fails is the lightdm-gtk-greeter 1.1 build, at link time:

  CCLD lightdm-gtk-greeter
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/liblightdm-gobject-1.a(liblightdm_gobject_1_la-user.o): undefined reference to symbol 'g_file_monitor'
/usr/bin/ld: note: 'g_file_monitor' is defined in DSO /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libgio-2.0.so so try adding it to the linker command line
