I started to try encrypting files. As my 1st attempt I installed Crypt::RSA module -- which downloaded & installed the PARI software. The latter generated large numbers of warnings but apparently installed ok. But when I run the simple script below I get this error.. 
PARI: *** exponent overflow at /Library/Perl/5.12/Crypt/Primes.pm 

Mac OSX 10.8.5

This is perl 5, version 12, subversion 4 (v5.12.4) built for darwin-thread-multi-2level
(with 2 registered patches, see perl -V for more detail)

#!/usr/bin/perl

use Crypt::RSA;

my $rsa = new Crypt::RSA; 

my ($public, $private) = 
    $rsa->keygen ( 
        Identity  => 'Lord Macbeth <macbeth@glamis.com>',
        Size      => 256,  
        Password  => 'A day so foul & fair', 
        Verbosity => 1,
    ) or die $rsa->errstr();
print $public;
