My Webrick session in irb is denying me any access. see output below:

[2015-08-15 08:40:05] INFO  WEBrick 1.3.1
[2015-08-15 08:40:05] INFO  ruby 2.2.2 (2015-04-13) [i686-linux]
Errno::EACCES: Permission denied - bind(2) for [::]:80

Obviously my options didn't through.

The error was simple. I did not capitalize port.
