It has been awhile but if you use the first CD or boot from the DVD, 
you have the option of a rescue mode.  This gives you a basic system 
but I don't know how many tools.  I believe that rpm is available from 
the rescue mode.

I would have to search the RH site to confirm what is available. 
Maybe someone else can assist from here.
