@AnonymousMonk - Since I am fairly new to Perl and Linux, I did not feel comfortable proceeding with the install until I knew exactly what was causing the problem. I didn't want to do a 'broken install' and then have to go back and fix something I really don't know how to fix! And thank you for the clarification on 'hostname.' I was assuming it was a Linux system var or Perl var.
@Almut - Thank you for the explanaion and a direction to pursue!
