Installing numpy on Docker Alpine

I'm trying to install numpy in a docker container based on Alpine 3.1. I'm using the following Dockerfile:

FROM alpine:3.1
RUN apk add --update make cmake gcc g++ gfortran
RUN apk add --update python py-pip python-dev
RUN pip install cython
RUN pip install numpy

This runs fine until
pip install numpy
when I get the following error:

error: Command "gcc -fno-strict-aliasing -Os -fomit-frame-pointer -DNDEBUG -Os -fomit-frame-pointer -fPIC -Inumpy/core/include -Ibuild/src.linux-x86_64-2.7/numpy/core/include/numpy -Inumpy/core/src/private -Inumpy/core/src -Inumpy/core -Inumpy/core/src/npymath -Inumpy/core/src/multiarray -Inumpy/core/src/umath -Inumpy/core/src/npysort -I/usr/include/python2.7 -Ibuild/src.linux-x86_64-2.7/numpy/core/src/private -Ibuild/src.linux-x86_64-2.7/numpy/core/src/private -Ibuild/src.linux-x86_64-2.7/numpy/core/src/private -c build/src.linux-x86_64-2.7/numpy/core/src/npymath/ieee754.c -o build/temp.linux-x86_64-2.7/build/src.linux-x86_64-2.7/numpy/core/src/npymath/ieee754.o" failed with exit status 1

easy_install-2.7 numpy
gives the same error.

Are there any config/installation steps I'm missing?

If you don't necessary need to install numpy from pypi, you could install it from alpine repositories. Package is named py-numpy and is in testing repository, see here. Minimal Dockerfile example that works for me

FROM alpine:3.2
ADD repositories /etc/apk/repositories
RUN apk add --update python python-dev gfortran py-pip build-base py-numpy@testing
