Thanks to all.

Then I will shortly start by disabling C++11 based of the value of
configure.cxx_std_lib. Ideally though I would like setting it instead,
but how can I test the package on a version of OS X which I don't own?
Are there porter boxes remotely accessible somewhere?

Kind regards, Thibaut.
