I never did get the perl CPAN dependencies squared away on two different CENTOS boxes.  Not sure where I went wrong but ran out of patience at the time.  Never could resolve whatever dependency caused

Can't locate JSON/RPC/Client.pm

I appreciate the gentleman running Multiclone but I'd like to run one myself for my own use.  I guess I need to try again sometime, perhaps with a newer distro than Centos 5
