Docker-compose build gives huge error

Hi all

I am trying to get this thing to build, and on the off chance that I am screwing up, I have not touched any config files. Tried to build it as it is cloned, but running into a major error. Could someone please point me in the right direction?


CentOS 7.5
Python 2.7.5
docker-compose version 1.18.0, build 8dd22a9
Docker version 1.13.1, build 6e3bb8e/1.13.1


docker-compose build
