It breaks on 10.1 with the c++11 -related message:

In this particular case, because 10.1 doesn't have r278724 [1], which
updated libc++ in stable/10 to the latest version in head.
This was an upstream libc++ bug [2], fixed in upstream r202994 [3].
I think this can be worked around by removing the '=3D' sign, but I =
can't
verify it at the moment.
