Scipy build (did not look into this yet and have to say I am not real
familiar with the issue)
python2.7 setup.py build

If you think it is a problem in numscons, you can also try executing the
scons
command with --log-level option for more detailed output of what numscons is
doing, for example --log-level=0; the lowest the level is, the more detailed
the output it.
