installer le module scipy sur centos

J'utilise centos, et j'ai installé python2.7 alternativement à la valeur par défaut de python. Je suis en mesure d'installer les modules que je veux avec le pip, mais je ne peux pas installer scipy. Quand je fais

sudo /usr/local/bin/pip2.7 install scipy

C'est le téléchargement, mais j'ai ce message d'erreur:
