The problem is that there is no such thing as a "quick and dirty" way
to build with optimized libraries, because the way to build numpy with
optimized libraries depend on many parameters.
I think the problem is that the process is too arcane/complicated, and
I strongly believe in making this easier instead of documenting all
the idiosyncraties 
 For example, this WE, I added support so that we can now finally
do this for NumPy:
with the options clearly documented in bentomaker configure --help
