If I understand Travis correctly, the idea is to use Numeric as the 
basis for scipy_core, allowing current Numerical Python users to switch 
to scipy_core with a minimum of trouble. So why not use Numeric's lite 
lapack library directly? What is the advantage of repeating the c code 
wrapping (by f2py or by hand)?
