Just FYI, I've noticed that the first test of LWP::Protocol::https fails because sometimes, when it tries to connect to the Apache Software Foundation, it connects ok; sometimes, it can't make a connection. For example, I installed it on 5.8.8 with no problems. A couple of hours later, I tried it on 5.16.0, but it couldn't connect. It seems the site is up and down frequently.

The modules are installed, so they should just work. I think that LWP needs to be told to do https, at least in this situation:

#!/usr/bin/perl -l

use strict;
use warnings;
use LWP::UserAgent;

my $ua = LWP::UserAgent->new(
    ssl_opts => { verify_hostname => 0 },
    protocols_allowed => ['https'],
);

my $req = HTTP::Request->new( 
    GET => 'https://api.flickr.com/services/rest',
);

my $res = $ua->request($req);
print $res->code;
