Error in FindNumPy.cmake

> What steps will reproduce the problem?
1. Use on a system that does not have NumPy

> What is the expected output? What do you see instead?
I expect the script to properly handle the case where "import numpy" fails. The 
output instead looks as follows:

> What version of the product are you using? On what operating system?
I am using the attached FindNumPy.cmake script in Ubuntu 12.04. Note that it is 
slightly modified, but that these modifications should not effect said bug.

Not sure what you are wanting to use numexpr without numpy.  Also, why are you 
using cmake for compiling numexpr?  numexpr is a package to be used with numpy, 
and indeed it raises an `ImportError` when using distutils for compiling the 
thing.
