You know, just after sendig my email I looked at your gitlab and saw that I 
can login with my github/gitlab/google credentials (I was hoping I wouldn't 
have to create yet another login) and I'm actually considering sending a PR 
to update the instructions :)

Agreed!

FWIW, CentOS 7.5 still has gcc 4.8.5, I'm guessing boost 1.57 was compiled 
with SCL's devtoolset-7-gcc (7.3.1):
