Oh, looks like you're right...
Is it strictly needed for some case that helloworld1 doesn't depend on
libgmodule-2.0.so.0, or is this a rather cosmetic feature?
Is this to allow pango to drop the "libgmodule" dependency and probably
replace it by something else, without the need to recompile helloworld1?
