But this will cause trouble anyway. Imagine this case: glib changes SONAME, 
both app and library depend on glib. app is recompiled, gtk isn't yet.So 
then app NEEDED libglib-2.0.so.1, gtk NEEDED libglib-2.0.so.0. Kaboom! The 
only real solution is to make gtk's SONAME dependent on glib's, eg libgtk-
x11-2.0.so.0-glib-1 (a la boost upstream with gcc versions).
