  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?
