출처 : https://gist.github.com/stephenturner/e3bc5cfacc2dc67eca8b

sudo rpm --import http://ftp.scientificlinux.org/linux/scientific/5x/x86_64/RPM-GPG-KEYs/RPM-GPG-KEY-cern

cd /etc/yum.repos.d/

wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo

sudo yum install devtoolset-2

scl enable devtoolset-2 bash ## set environment variable

현재 사용중인 AMD 시스템에서 gcc-4.9.2 사용하려면 

# scl enable devtoolset-3 bash

할것.
