[Fedora-spins] revisor-like tool available?

Hi,

Hopefully I am posting to the right forum.  I am looking for a tool to change the default
Fedora Core 16 package set in the DVD distribution.  revisor looked like a good candidate,
but it turns out it hasn't worked for some time ("revisor doesn't
start", "Cannot find anaconda-runtime in /usr/lib/anaconda-runtime",
https://bugzilla.redhat.com/show_bug.cgi?id=649815).

Can someone point me to something that might fit the bill?  Thanks in advance.
