OK, fair enough.

OK, so it seems our testing logic (at least) actually requires a more
recent Python version. At this point in time I'm not sure how much
effort it is worth spending on the testing harness to support older
version of Python. And since you aren't interested into Boost.Python
yourself, perhaps it would be easier if you disable it alltogether in
your test runs, so as to reduce your testing workload and reduce the
noise in the Boost.Python test matrix.

OK, thanks !
