I am trying to install `scipy` and `numpy`. Because I don't have root privileges, when I tried to install `numpy` first, I typed `python setup.py install --prefix=/data3/home` which worked. When I then tried to install `scipy` it reported this error:

```
File "setup.py", line 230, in <module>
    setup_package()
  File "setup.py", line 218, in setup_package
    from numpy.distutils.core import setup
ImportError: No module named numpy.distutils.core

```

How can I fix this issue?
