I have CentOS 7 and I have installed mpicc (it works and compiles for openmpi in C). I also have python 2.7.5 and just installed pip. I'm running this command and get the following errors:

```
sudo pip install mpi4py

I tried every solution I found so far and none seemed to work, has anyone any idea about this problem, please? Thank you
