Yes, you need to to install NumPy first.  SciPy also needs a functional 
LAPACK and BLAS installed (or use ATLAS).

I have not heard of any successful CYGWIN installation.  But that 
doesn't mean it's not possible --- nobody has yet contributed the 
details necessary to get it to work.  I think we just need to get a 
couple of auto-configuration things fixed.

1) What are the errors you are getting?  

2) There is going to be some need to define the appropriate functions in 
ufuncobject.h to handle the IEEE error-setting correctly.
