That's as normal as c++ can be :) Sparsetools relies on SWIG +
templates, which are both performance killer as far as compilation is
concerned. Sparsetools currently accounts for ~ 50 % of the whole scipy

I don't know, those have always confused me. AFAICS, those are reliques
from old scipy code, I don't think they matter (I think we should remove

This one is new to me, I have never seen it before. Looks like a problem
with gfortran on mac os x. We should first see if the issue stays with
the following issue:

I think whatever issue happens with the actual gcc version should be
fixed - we should not rely on gcc 4.0 on Snow Leopard, and this is not
needed (the -mlong-branch warning is linked to this).
