You don't have the module installed, and you'll have to install the module, I'm afraid. If you have root access (or you can get the admin to do this for you) I'd advise using the CPAN module.

perl -MCPAN -e 'install Term::Readkey'
[download]

from the command line. Read perlmodinstall for more info on installing modules.
