# install openBLAS
apt-get install git python-dev gfortran
mkdir ~/src
cd ~/src
git clone https://github.com/xianyi/OpenBLAS
cd OpenBLAS
make FC=gfortran
make PREFIX=/opt/openblas install
sh -c "echo '/opt/openblas/lib/' > /etc/ld.so.conf.d/openblas.conf"
ldconfig


# install Python headers
apt-get --yes --force-yes install python-dev
