I think there's an implicit assumption here that you are installing 
shared libraries *meant to be picked up by the dynamic linker*. Some 
packages ship dynamic libraries that are dlopened() directly by the 
application (plugins), in that case calling ldconfig will not do 
anything and so is not necessary.
