Newer versions of build-time package are available (eg, gcc, valgrind, make, etc) and run-time packages too (python, ruby, php, git, mariadb, maven, nodejs, perl, java, nginx, mysql, mongodb, postgresql, redis, etc).
And there are other related RPMs (fortran, c++, etc.). To see what is available run the command
yum list devtoolset-4\*scl -l
# look for the latest version of devtoolset, eg, devtoolset-6 as of June 2017
yum | grep rhscl
The yum repo for SCL is SLAC RHEL6 Server Software Collections (slac-rhel-x86_64-server-6-rhscl-1). These are installed on public login hosts, if you do not have sudo on a host where it is needed, please send an email to unix-admin@slac.stanford.edu.
