Can't install ptop on CentOS 7

Hi,

I am trying to install ptop on CentOS 7 without success.
The error I am getting is:

> psutil/_psutil_common.c:9:20: fatal error: Python.h: No such file or directory
> #include
> ^
> compilation terminated.
> error: command 'gcc' failed with exit status 1

I understand that it says I need Python.h but there is no one. With what should it be comming?

EDIT: I have tried with yum install python34-devel but I get the same error.
