Using "yum install python33-numpy " could be a solution for numpy but this just 
forward the problem to the next package I have to install with pip. I do not 
understand why a python 3.3 environment try to install incompatibles packages.

I tryed to install python34 with yum but it does not seem to work with scl 
environment.... (yum install python34-setuptools python34)
