I was installing freepbx on Centos 7 following wiki:
https://wiki.freepbx.org/display/FOP/Installing+FreePBX+13+on+CentOS+7
Saw that ikesemel has switched repo and instructions these steps should work:
yum install python-devel
git clone https://github.com/meduketto/iksemel.git
cd iksemel/
./autogen.sh
./configure
make
make install
