  [File not found: /builddir/build/BUILD/ndppd-0.2.5-build/BUILDROOT/usr/bin/ndppd]: [There is a file listed, but not installed]

Issue: There was a Fedora change of unification of the /usr/bin and /usr/sbin (https://fedoraproject.org/wiki/Changes/Unify_bin_and_sbin) which is breaking this package, because it installs the files to unexpected folder.
Resolution: Add the `SBINDIR=%{_sbindir}` to the `%make_install` macro
