The file is not missing, it's marked %ghost.

There is no way that we can distribute the file, as the file contains the names
of NTP servers that should be used to set the clock, and that is up to the
system administrator, not Red Hat.

(1) I don't know what "%gohst" really is supposed to do (and the rpm
documentation dosn't
really help). I don't understand what sense it makes to add a file to the
database this way -
will it be removed on extraction of the rpm?
Such files should be tagged as "missingok"! 

(2) I could not find any reference to a file named "step-tickers" in the
documentation. In addition, the file which contains the servers is ntp.conf!
So if the file is nothing good for, remove it from the package.
You should rather add the drift file /etc/ntp/drif as %ghost(missingok)

The file /etc/ntp/step-tickers contains the name of one or more hosts to
synchronize
time form before starting ntpd. The only use is in /etc/rc.d/init.d/ntpd.

Marking a file %ghost is useful for files (like step-tickers) that are
configured per machine.
The content of the file is not in the package, but the ownershiip and
permissions are. That
permits "rpm -V" to be used to verify that the file has correct uid, gid, and
permissions no matter what is in the file.

Adding /etc/ntp/drift probably should be marked %config(missingok), we'll get
there eventually.

Fixed (/etc/ntp/drift marked with %ghost %config(missingok)) in ntp-4.0.99k-2.
