[Numpy-discussion] lapack too small?

Hey Mathew

The problem is that ATLAS doesn't provide all the LAPACK functions, only a
few that the ATLAS developers have optimized.

To get a complete LAPACK library, you need to build the Fortran LAPACK
library, and then put the ATLAS-optimized functions into this library.

Details here:

Albert
