Hi everybody,
I am not really familiar with the Py subsystem, even though I have got some
guidance from some colleague, I am getting stuck when installing a list of
packages contained in a file, running such command :
pip install -r /home/pietro/projects/cloud-provisioning/requirements.txt
Brings me :
Collecting docutils>=0.10 (from botocore<1.4.0,>=1.3.0->boto3==1.2.3->-r
/home/pietro/projects/cloud-provisioning/requirements.txt (line 9))

It looks pretty confusing to me since I can't fix it just installing some
packages, have you any idea about why is this happening ? I am running on a
Debian linux distro. I do not have any problem to manually install "pip
install cryptography" which works fine.
What does "Building wheels for collected packages: cryptography,
gnureadline" mean ?
