would you be kind to elaborate?  alternatives is a pretty much a
'symlinks' manager to alternate between alternative implementations.
That is why imho they work neatly for blas/atlas management.  Here
I see a similar use case if all those builds provide identical API/ABI.
I would hate to build ants-mpich,  ants-openmpi, ants-serial to provide
alternative linkages.

Or am I missing the point?
