are they maintaining it?

 (also pretty old -- I see this:)

- Numpy (numpy.scipy.org) (Tested versions: 1.1.1, though >= 1.0 should work)
- Python (www.python.org) (Tested versions: 2.5.2, though >= 2.3 should work)

both pretty old versions.

also pretty old.

So I'd go with the actively maintained on -- or Cython -- what I can
tell you is that Cython is being very widely used in the
numerical/scientific computing community -- but I haven't seen a lot
of Boost users. Maybe they use different mailing lists, and dont go to
SciPy or Pycon...

I'm not sure you made your use case clear -- are you writing C++
specifically for calling form Python? or are you working on a C++ lib
that will be used in C++ apps as well as Python apps?
