You'll probably need to build an rpm database in the jail (put rpm in there as well) Trial and error can get you a long way. I'm an apt man myself, but I would try using rpm itself to install everything in the jail, something like:

rpm --root=/jail --initdb
rpm -ivh --root=/jail rpm-*.*.rpm
rpm -ivh --root=/jail up2date-*.*.rpm

etc.

P.S. You'll probably need a /var/lib/rpm in the jail, initdb might make one, then again might not.
