wish to install firewalld 0.4.1.2 on CentOs 7

[Rubén Rivero Capriles]

I notice in ./configure that:
checking for python version... 2.7
checking for python platform... linux2
configure: error: glib-compile-schemas not found.

My current python version is 3.5 which I installed yesterday. How can I get rid of 2,7 ?
I had many firewalld conflicts today with the pythos 3.5 I installed yesterday. Iptables didn't work either. So I uninstalled both of them and downloaded from source firewalld-0.4.1.2.tar.bz2
After README I notice there are many important files for installation: Firewalld.spec Makefile.am Makefile.in fix_python_shebang.sh py-compile
How should I continue installation? Below is output from my recent failure of previous version of firewalld

sudo firewall-cmd --permanent --add-service=http
