scp command included to openssh base rpm. But it really belongs to openssh-client, as it *is* a client by itself obviously, and it depends on ssh command included into openssh-client only. Note that this is an issue for *all* openssh versions on all redhat distros. No patch included as it is trivial to do (move two lines between two %files section in .spec file).
The scp binary actually implements both the client and server sides of the scp protocol, so it's neither a client nor a server proper, and likely belongs in the main package, if only for lack of a better place to put it.
