That doesn't look like it has anything to do with the version of Perl in 
use on your machine, ancient though it may be. It appears your perl 
explicitly ignores SIGINT by default, which get_iplayer doesn't expect. 
  Please run the command below and reply with the result:

perl -e 'while ( ($k, $v) = each %SIG ) { print "$k=$v\n"; }'
