As advised, installing the missing "openssh-clients" on the nameserver VPS's solved the issue and the install script ran successfully as describe on virtualizor.com/wiki/PowerDNS

However when your script gets to
slave-ns it fails, please see the error below, Here's your tutorial. Rather simple yet it fails. /wiki/PowerDNS

Please note my parameters are correct,

I do not want to hand over my root pass every time there is a problem.

Both of my ns servers and the virt server can all ping each other ,
remote ssh is enabled everywhere, both ns servers have centos 6.4-64bit,
512ram 10gb HD, 4 vCPU. Both ns servers are vps, both are on different
subnets, I set SELinux as disabled on both ns servers. For test purposes
I successfully used 'scp' to copy a random file to and from both ns
servers to confirm connectivity.

What should I investigate to resolve this issue?

Should I try install MySQL manually on the slave ns server and then
re-run your PDNS install script on the master ns server to try resolve
this issue?

Should I try add both ns servers(as PowerDNS servers) to my virtualzor
server config area before running the install script on the master ns
server?

The log is below, same issue, please be advised my parameters are 100%
correct.

Here's the log,
