Certo, ecco qua:

 $ python -c "import ssl; print(ssl.OPENSSL_VERSION)"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'OPENSSL_VERSION'

Questo è un python 2.6.5: interessante :D

Con un python 2.7 compilato da me:

 $ /opt/python-2.7.2/bin/python -c "import ssl; 
print(ssl.OPENSSL_VERSION)"
OpenSSL 0.9.8k 25 Mar 2009

e funziona ancora il codice sopra mentre con un python 3.1 (sempre 
compilato da me, sullo stessa macchina degli altri due interpreti:

>>> import urllib.request as urllib2
>>> x=urllib2.urlopen('https://www.u-gov.sssup.it')
Traceback (most recent call last):
  File "/opt/python-3.1.1/lib/python3.2/urllib/request.py", line 1136,
