I wonder whether the installer could be: by default, smallish, with just numpy, with the option of pulling down the lapack libraries from the web on installation or, possibly optionally, large, with the lapack libraries installed by default. I was thinking, that if that were the case, then installing scipy from source might go from being very nasty (needing a compiled blas / lapack), to only fairly nasty (needing fortran), making it more accessible.
