sage itself would probably be fine with reference I think. However linbox and historically ghmm (now gone) need clapack which is provided by lapack-atlas. Actually _you can_ build lapack-atlas using blas-reference not very efficient but doable. For the rest I need to check if linbox is linked in sage - if it is then you run the risk of linking with multiple versions of lapack. Which actually given how sage is built may not be such a big problem. Francois
