Raspberry pi - get-pip.py error

I'm working on a Raspberry pi 2 with piface. I'm trying to install openCV by following this steps : click here. When I try doing the step 6 (install pip), I got the following error :

To be completely honest, in order to authenicate using --noauth_local_webserver, I run the command with sudo, authenticated and chown the gmail.storage to myself again.
Also, I installed using easy_install because pip install was giving me the following error:

It is my understanding that the root of the problem is the same in both cases.
I also have to note that my laptop (on which I can authenticate normally, on webbrowser, instead of --noauth_local_webserver) it works just fine, even though the installation is done the same way (the problem with pip appears there too).
Thanks in advance and sorry for the long post!
Tutorials I used:

The httplib2 installer sets incorrect permissions for its httplib2/cacerts.txt file. One solution is to simply make its files readable by anyone by running
chmod o+r -R /usr/local/lib/python2.7/dist-packages/httplib2-0.9-py2.7.egg
However, it may be better to uninstall the version installed by pip, and use your operating system's package manager instead, which probably has the correct permissions for all files. On Debian, this could be accomplished with
pip uninstall httplib2
apt-get install python-httplib2

Cannot use Google Native Client SDK on Windows 7

I am trying Google's Native Client SDK.
OS is Windows 7, I've already installed python 2.7.9 and setup the environment variable path accordingly.
I also downloaded nacl_sdk.zip from https://developer.chrome.com/native-client/sdk/download and extracted it.
However, as I run the command "naclsdk list" as it is described on the download page, I got the following messages:

Does anyone understand where it comes from?

For me it actually failed with socksipy-branch installed with pip.
However, it worked ok after I downloaded socks.py directly from http://socksipy.sourceforge.net/ to my working directory.

It looks like you are using the SocksiPy library. I had the same problem and got it fixed by installing this library again directly from https://code.google.com/p/socksipy-branch/. The first time I installed it via pip.

timeout: timed out
Is there a way to prevent these timeouts? why do they happen?

The index server failed to respond, the connection timed out. This happens when PyPI is down, for example. By default, the index server is http://pypi.python.org/simple, but you can set your own with the [buildout] option index.
We use an egg proxy (set up with collective.eggproxy) to create a local cache automatically, to avoid such problems. Our buildouts use that server as the index, and the proxy will download any missing packages from PyPI and cache them locally. So, for any packages that we have used in the past, we can continue to serve even when PyPI is (temporarily) down.
