Looks like a networking problem. Can you access this from the command line of the machine in question? If not then you need to speak to your sys/network admins. If you can you may still need their help to configure cpan, e.g. WORKING WITH CPAN.pm BEHIND FIREWALLS. FWIW cpanm has fewer dependancies. I work mainly offline using a cpan mirror created by minicpan, copied onto our clients network, with no internet access.
