The official SL6 link is at:


And for SL7:

Upstream has not published any EL7 packages for devtoolset.  So, right 
now there really isn't anything to build.  Without promising anything, 
SL is interested in this technology.

I've built up the EL7 SCL from 
ftp://ftp.redhat.com/redhat/linux/enterprise/7Server/en/RHSCL/SRPMS/ but 
it is not clear that these are officially released by upstream, so 
they've not been published for SL7.
