Good morning,
We were able to resolve this by adding http://us.archive.ubuntu.com & http://security/ubuntu.com to our proxy server allows.
I was then able to run an apt-get update and then apt-get install libssl-dev. That enabled me to finish the source code compile using ./configure --prefix=/apps/nagios --enable-command-args --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib/x86_64-linux-gnu > /dev/null
Thanks for you all your help.
Rick
