Ok, I assumed as much and proceeded by simply setting the environment variable.  I did not add the part where you said 
	python -c "import numpy"

What does that part do?  It turns out that by fixing my library path, numpy now imports.  I assume that my installation of h5py doesn't need to be redone just because I reinstalled Numpy?
