Hi Oscar,

I downloaded the file 
https://pypi.python.org/packages/source/s/setuptools/setuptools-14.0.tar.gz

tar -xzvf setuptools-14.0.tar.gz
cd setuptools-14.0
python3 setup.py install

Then I downloaded the file 
https://pypi.python.org/packages/source/p/pip/pip-6.0.8.tar.gz
tar -xzvf pip-6.0.8.tar.gz
cd pip-6.0.8
python3 setup.py install

And the command python3 -m pip list

pip (6.0.8)
setuptools (14.0)

But the command to install numpy gave an error message:

# python3 -m pip install numpy

Collecting numpy
   Exception:

   TypeError: wrap_socket() got an unexpected keyword argument 'ciphers'

Should I use older versions of pip and setuptools compatible with Debian 6?

Thanks for your attention,
