Pourquoi ma nouvelle Ubuntu 12.04 est incapable de vérifier un certificat ssl de Verisign ?

En bref : Cette demande échoue.

$ curl 'https://secure.ogone.com/ncol/prod/orderstandard.asp' -vv
* About to connect() to secure.ogone.com port 443 (#0)
*   Trying 213.254.248.101... connected
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* Unknown SSL protocol error in connection to secure.ogone.com:443 
* Closing connection #0
curl: (35) Unknown SSL protocol error in connection to secure.ogone.com:443 

Je suis conscient des risques de sécurité liés à sslv2, qui nécessitent que certaines connexions soient manuellement configurées en sslv1 ou sslv3.

Mais cela ne fonctionne pas non plus :

$ curl 'https://secure.ogone.com/ncol/prod/orderstandard.asp' -3
curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

Si je visite le site web dans un navigateur web, le certificat se vérifie sans problème.

J'utilise une image ubuntu 12.04 nue provenant du cloud amazon aws ec2 (64 bits, un des modèles standard de l'assistant ec2...).

Je ne sais pas vraiment comment commencer à déboguer cela, pourriez-vous m'indiquer la bonne direction ?

voici d'autres informations qui pourraient vous être utiles :
