I was getting: cURL error: [60] SSL certificate problem, verify that the CA cert is OK.

Then I read this: http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/

I've added in ipnlistener.php this:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

on function curlPost() after "curl_setopt($ch, CURLOPT_HEADER, true);" (around line 103)

I think this needs the "proper fix", maybe you should bundle PayPal CA certificate along with the example?.

Thank you very much.
