Here's a basic, non-golf implementation as a starter.

#!/usr/bin/perl -w
use strict;

my $secret = shift;
until (length $secret == 1) {
    print "$secret\n";
    $secret = tpr($secret);
}
print "$secret\n";

sub tpr {
    my @digits = split //, shift;
    my $not_so_secret;
    while (my @pair = splice @digits, 0, 2) {
        unshift @digits, $pair[1]
            unless !@digits;
        my $res = $pair[0] + $pair[1];
        until ($res <= 9) {
            my $cpy = $res;
            $res = 0;
            for (split //, $cpy) {
                $res += $_;
            }
        }
        $not_so_secret .= $res;
    }
    return $not_so_secret;
}
