The documentation is correct (if a bit confusing):
- In general, it is not necessary to call ldconfig after installing
shared libraries (because that is handled by a file trigger in RPM).
- However, that file trigger only handles the case where libraries are
installed in %_libdir, so if you install somewhere else, you still
need to call ldconfig.
