I thought this was todo with the requirement for python 3.5, so I installed

yum install devtoolset-6-toolchain devtoolset-6-perftools rh-python35

scl enable devtoolset-6 rh-python35 bash

and retried building and got the same error.

Shouldn't the cmake scripts be checking for python versions, and required
modules etc.
