CentOS 6上带有Mojolicious的HTTPS请求

#!/usr/bin/env perl 
#===============================================================================

use strict;
use warnings;
use utf8;
use feature ':5.10';
use Mojo::UserAgent;

our $ua = Mojo::UserAgent->new();
$ua->transactor->name('Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0');

my $res;

$res = $ua->get('https://example.org');
if ($res->error) {
    print "error\n";
    print $res->error . "\n";
    print $res;
} else {
    print "success";
}



CORE
  Perl        (v5.10.1, linux)
  Mojolicious (6.66, Clinking Beer Mugs)

OPTIONAL
  EV 4.0+                 (n/a)
  IO::Socket::Socks 0.64+ (n/a)
  IO::Socket::SSL 1.94+   (n/a)
  Net::DNS::Native 0.15+  (n/a)

但剧本上印着“错误”。问题似乎是没有安装IO::Socket::SSL 1.94。但我在CentOS 6找不到它。
