Is there a difference between --install-option="--user" and just
passing --user directly?

To be clear any of the above options are for building scipy from
source which means you need a C compiler, a Fortran compiler and to
separately build/install BLAS/LAPACK:
http://stackoverflow.com/questions/7496547/python-scipy-needs-blas

The best instructions for meeting these requirements depend on your OS
(are you using Windows?).

For Python 2.7 I think that easy_install will be able to install from
the sourceforge binaries, e.g

    easy_install --user scipy

but I may be wrong.

You'll need to ensure that you don't have a mismatch between
numpy/scipy versions and I don't know if easy_install will handle that
for you. This may mean separately installing numpy as well.
