[BioPython] Install issues - *** Numerical Python *** is either not installed or out of date

[Allan Kamau]

Hi all,
Am attempting to install biopython-1.47.
I have installed the prerequisites for  biopython including numpy 
(http://numpy.sourceforge.net/).
When I run setup.py build, i get the message below. I am sure I have 
installed numpy correctly as I can do "python -c 'import numpy; 
numpy.test()';" and not receive an error.

I think Numerical Python package had a name change some time ago from 
"Numeric" to "numpy" (meaning that import Numeric will more probably fail)

What can I do?

"*** Numerical Python *** is either not installed or out of date.

This package is optional, which means it is only used in a few
specialized modules in Biopython.  You probably don't need this if you
are unsure.  You can ignore this requirement, and install it later if
you see ImportErrors.
You can find Numerical Python at http://numpy.sourceforge.net/.

Do you want to continue this installation? (Y/n)  n
