This will allow build script like "build-wheels.sh" to run command like
the following (see [1]):
sudo yum install -y atlas-devel
It will also allow to pip install using sudo and avoid error reported in [3].
That said, instead of running pip using sudo, the recommended approach
is to specify the "--user" flag [2]

[2] http://stackoverflow.com/questions/7143077/how-can-i-install-packages-in-my-home-folder-with-pip#7143496
[3] Error reported when running pip without "sudo pip install <packagename" or "pip install --user <packagename>"
