Give that a shot.
A quick explaination of a proxy server is a server that clients, usually
browsers on people's desktops, connect to that then turns around and
gets the web page from the internet.
People usually install them to save on bandwidth (the server can cache
images, which is helpful if hundreds of people go to the same website)
and when they want to restrict what IPs can go out the internet or what
websites people can go to.
In your case the admin has probably turned off all web access to clients
not going through the proxy server. Since you didn't tell CPAN to use a
proxy server it tries to connect to the website directly, thus the
admin's firewall is blocking your request.
