Description of problem: # pkg-config --libs gtk+-2.0 -Wl,--export-dynamic -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangoxft-1.0 -lpangox-1.0 -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0 this --export-dynamic is caused by /usr/lib64/pkgconfig/gmodule-2.0.pc the ripple-through is that most of our desktop is using export-dynamic, causing lots of load time overhead and disk usage
This has been fixed upstream in glib 2.6 by introducing gmodule-no-export-2.0.pc, and using it at least in pango and gtk.
