That works for me with the patch.

I suggest building the wheel against the python.org python; the wheel
is then compatible with system python, homebrew etc - see :

https://github.com/MacPython/wiki/wiki/Spinning-wheels

I then rename the wheel to express the fact it is compatible with
these versions, with something like the attached script.

This ends up renaming the default output wheel:

pyviennacl-1.0.3-cp27-none-macosx_10_6_intel.whl

to this:

pyviennacl-1.0.3-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.whl

Here are checks showing that this build / rename process does in fact
work for homebrew, macports for numpy / scipy / matplotlib / pandas
etc (the failures are real test failures, not packaging errors):

https://travis-ci.org/matthew-brett/scipy-stack-osx-testing/builds/25131865

(thanks to Matt Terry for the basis of the script to do this testing).

I checked with the `delocate` `delocate-listdeps` utility, and you are
only linking to stuff in the OSX System directories, and you don't
need to use `delocate-wheel`.

Cheers,

Matthew
