devtoolset-1.1 install falha com o contêiner do Docker Centos 7 depois de trabalhar por meses

Question

Isso funcionou até recentemente.

yum -y install wget gmp-devel rpm-devel mpfr-devel rpm 

wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo 
rpm --import http://linuxsoft.cern.ch/cern/slc6X/x86_64/RPM-GPG-KEY-cern 

yum install -y  devtoolset-1.1

Os erros são:

Todas essas coisas, como libgmp, estão instaladas. As versões não são as mesmas, no entanto.
