Also versuche ich, meinem Webserver, der auf meinem pi B + läuft, SSL hinzuzufügen (mit cherrypy).
Ich habe sichergestellt, dass OpenSSL installiert wurde mit:
sudo apt-get install openssl
Dann habe ich pyOpenSSL installiert mit:
sudo apt-get install python-openssl
In beiden Fällen heißt es:
openssl is already the newest version.
python-openssl is already the newest version.
Weil ich den Befehl mehr als einmal ausgeführt habe. Das scheint also in Ordnung zu sein.
Bis dahin in Python, wenn ich:
import OpenSSL
Ich bekomme Fehler. Speziell:
Python 2.7.3 (default, Mar 18 2014, 05:13:23)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Habe ich hier ein Kompatibilitätsproblem? Sind die beiden neuesten Versionen nicht miteinander kompatibel? Hat das schon mal jemand gesehen?
Die Versionsinformationen, die ich habe:
% openssl version
OpenSSL 1.0.1e 11 Feb 2013
Und für Python-OpenSSL habe ich:
% dpkg -s python-openssl

Description: Python 2 wrapper around the OpenSSL library
High-level wrapper around a subset of the OpenSSL library, includes
.
* SSL.Connection objects, wrapping the methods of Python's portable
sockets
* Callbacks written in Python
* Extensive error-handling mechanism, mirroring OpenSSL's error
codes
.
A lot of the object methods do nothing more than calling a
corresponding function in the OpenSSL library.

Wenn ich das Flag -v auf Python verwende, bekomme ich:
