nessus-mkcert failing

[Shawn Saunders]

I am running the current stable build of Nessus on Redhat 7.1. I've tried the nessus-install.sh script and the lynx process as-well-as building all the libraries and core, etc directly and continue to get the same error.   When I run the nessus-mkcert it responds:   An error occurred while generating the certificates and/or keys !   Then asks if I want to save output to /root/openssl-output, which I do, I find in there that the keys are not created.   I have read the FAQ and searched the net, any insight would be welcome.   Shawn
