It means that you are rebuilding a package with a compiler version
which is too old to support the -std=c++11 flag. (IIRC, it was
-std=c++0x
for a long time in gcc. I don't recall which gcc version added the new
flag, but almost certainly it was later than gcc4.4, for example.) I
guess
you are backporting this package?

Hi Pete,
Ye old out-of-date strikes again. Probably will have
to wait for SL7. Rats!
devtoolset-1.1 has g++ (GCC) 4.7.2 20121015 (Red Hat 4.7.2-5)
which accepts -std=c++11
devtoolset-2.1 (which has g++ 4.8.?) is also available;
IIRC you may need go through devtoolset-2.0 if upgrading from 1.1 to 2.1.

These use scl and are designed to be installed *alongside* the
default gcc4.4
I now have the deltoolset installed, but still have the error.
What am I missing?
