Ubuntu :: Cannot Compile GTK Code After Update To Natty

After updating to natty I cannot compile any Gtk+ code, no matter what I do I get linker errors. This is not a problem with the way I'm building it, I'm familiar with the correct usage of pkg-config.

Even this code will fail to link:
Code:
#include <gtk/gtk.h>
int main(int argc, char** argv) {
gkt_init(&argc, &argv);
gtk_main(); }
(Compiled with the standard commands to compile Gtk+ stuff)

I always get the following output:
Code:
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_source_get_time'
/usr/lib/libgtk-x11-2.0.so: undefined reference to `g_get_monotonic_time'
/usr/lib/libgdk_pixbuf-2.0.so: undefined reference to `g_simple_async_result_take_error'
/usr/lib/libgdk-x11-2.0.so: undefined reference to `g_slist_free_full'
