Well, I've realized the copr is not named devtoolset-2, but just
devtoolset, which is not ideal.. and renaming is not possible in copr..
maybe it would be better if you'd create your own copr, which has
correct name..

Honestly, I don't know what is necessary to fix the builds, but since
they were failing, I expect something would need to be fixed.

The sources are available here:
http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/RHDevToolset/SRPMS/
Again, I don't know unfortunately, whether there were already some
modifications done, sorry.
