If I remember correctly, Revisor x86_64 is not working since Fedora 14. At the time I ended up working with livecd-creator. Today (in F16), however, I was curious to see if there were improvements in Revisor and find that the same bug "Cannot find anaconda-runtime in /usr/lib/anaconda-runtime" is still not resolved [1] [2].
The fix is kind of easy and already reported in Bugzilla.
Revisor is a great software and it is sad to believe that is abandoned.
