Error installing spksrc on 32bit Debian 7.5.0

[Wibout]

I try to install spksrc on a 32 bit virtual machine running Debian 7.5.0.

The requirements mention two commands that need to be executed.
The first one (sudo aptitude install build-essential debootstr...) gives the message below:
No candidate version found for bjam

The second one (sudo pip install -U setuptools pip==1.5.4 wheel==0.23 httpie) gives the message below:
Traceback (most recent call last):
File "/usr/bin/pip", line 5, in
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

What do I need to do to solve this issue?

Best regards,

Wibout

The pip version installed on the clean Debian 7.5.0 machine had version 1.1 and it seems this caused the problem. See http://pip.readthedocs.org/en/latest/distribute_setuptools.html

Maybe i resolved the problem...
I do:
wget https://bitbucket.org/pypa/setuptools/downloads/ez_setup.py
python ez_setup.py
pip install -U setuptools

and then i do
sudo pip install -U setuptools pip==1.5.4 wheel==0.23 httpie

and unless go OK.I have Debian 7.6 32bit
