Ok, this really bothered that you had to install sage to use numpy.
You don't have to do it since you already wasted quite some time, but
I updated a small project of mine that I almost forgot: garnumpy. It
is a set of makefiles to build numpy, scipy and all its dependencies
(blas, lapack, fftw, etc...) automatically:
  - It download the tarballs for you.
  - It installs everything in a configurable directory, so that it is

It is there;


You can get the sources with git or just the tarball generated by
github if you don't have/don't want git.

Basic usage:

set up main_prefix in the file garnumpy.conf.mk (or keep the default
value: it installs in $HOME/garnumpyinstall)
cd platform/scipy && make install
source startgarnumpy.sh
# You now have your env set up for numpy and scipy
python -c "import scipy"

If you want to remove it, just rm -rf the path set up in main_prefix.
