When you type 
from scipy import *
I think you also import the fft module from numpy (as there's a from numpy 
import * in scipy.__init__). So 'fft' is the package numpy.fft
When you type
from scipy import fftpack
the fft routine is available as fftpack.fft

So, if you wanna overwrite fft, you should do
from scipy.fftpack import *
