I see your point, but why not just install a separate NumPy to run 
with the system Python? That is what I have always done in the past 
without problems.

I guess I always feel a sense of uncertainty with having two separate 
Python installations as to which actually gets used in any particular 
situation. I appreciate that for experts who use Python daily, this 
isn't an issue, but for someone like myself who may have gaps of 
several months between projects that use Python, this is a real issue 
as I forget those kinds of subtleties.
