That error means that cpan could not connect to the outside world by using the FTP prototcol, and the error it got was a timeout.

The first thing to check is if the machine you're trying this on can reach the internet at all, and by which method. A common way is the HTTP protocol.

The next step is to reconfigure cpan to use a HTTP url instead of ftp, either by completely reconfiguring (Type o conf init in cpan) or by reconfiguring selected items (Remove all ftp items, and set up HTTP, if HTTP works for you)

Traditionally, the CPAN shell will try several options though, so something seems weird with your setup, as it only seems to try ftp.
