IIRC, those wheels are built for the pyton.org builds of python:
macosx_10_9 means it was built on 10.9 (though that should be 10.6, I
think, as it is built FOR 106+, not only 10.9..)
_intel means it's an Intel build, which in the nomenclature used in the
pyton.org builds, means it's a universal 32 and 64 bit Intel

What python are you using? apparently not a Universal 32+64 bit build. The
one Apple delivers?

I'm not entirely sure we can count on that working, as I _think_ the SDK
that the wheel was built against is different than the one your python was
built against.
But it theory, one should be able to install a universal wheel into a
one-of-the-architectures build, the other one will get ignored (as it seems
to be for you), but I think it's fragile in general.
This is a serious issue with binary wheels -- there are so many variations
to a "platform" -- the naming scheme covers OS, OS version, and bit depth,
but not system library versions, and who the heck knows what else.
This has been discussed a lot on the dist_utils list, with no real solution
in sight:
- there are other alternative, for instance, I think conda packages have
some sort of hash or something to make sure that binary packages all match.
- convention is the other option:
- use binary wheel for in-house deplyment to similar systems
- use binary wheels for a well-defined python build:
- for PyPi, that's the python.org builds for Windows and OS-
