I think that Andreas ment by "really not used" that the app doesn't
reference any symbols from the library (but is unnecessarily linked
against it).

Eg:
$ gcc -o a1 hello.c
$ gcc -lxyz -o a2 hello.c
$ ./a1
hello!
$ ./a2
hello!
# rpm -e libxyz libxyz-devel
$ ./a1
hello!
$ ./a2
./a2: error while loading shared libraries ...
