Indeed Anaconda is a large package. There is, however, a stripped down version called Miniconda [1], which installs just the "conda" tool and a version of Python (rather than the whole scientific Python stack). The Miniconda installer is a more reasonable size (40MB). The advantage of using conda over, say, pip is that there are conda packages for most non-python dependencies required for scientific computing, which means that there are fewer problems when it comes to linking, as conda knows about the whole software stack. > [lapack] > libraries = lapack refblas > library_dirs = . > extra_link_args = -Wl -lgfortran I am almost certain that this is a linking issue, e.g. Kwant is linked against some version of BLAS and LAPACK is linked against another, or something like that. Without being able to exactly reproduce your setup I probably won't be able to say any more than that. I would strongly suggest using conda; this will probably get you set up the fastest.
