Hi,

AlpinineLinux 3.3 has a patch for numpy to build it against musl - numpy-1.10.0-musl.patch <http://git.alpinelinux.org/cgit/aports/tree/testing/py-numpy/numpy-1.10.0-musl.patch?id=2e5c4bfcf1c9746edd58a8e684d01403f234e71d>
Actually the issue is fixed in numpy itself and should be available in the nearest release

Regards,
Dmitry
