What is the easiest way to install BLAS and LAPACK for scipy?

Question

I would like to run a programme that someone else has prepared and it includes scipy. I have tried to install scipy with

pip install scipy

Answer 1

I got this problem on freeBSD. It seems lapack packages are missing, I solved it installing them (as root) with:

pkg install lapack
pkg install atlas-devel  #not sure this is needed, but just in case

I imagine it could work on other system too using the appropriate package installer (e.g. apt-get)
