The newest development version atlas-3.9.32 now wants to build lapack itself and the old --with-netlib-lapack configure option is gone. According to the documentation, atlas can now automatically tune some lapack routines in addition to blas. From that perspective it makes sense that both need to be compiled together. But Sage currently ships separate lapack and atlas spkgs. I guess the options are
1) somehow figure out how to separate atlas and lapack. That seems to be on collision course with where atlas is heading... 2) include lapack in the atlas spkg (versioned by lapack) 3) include atlas in the lapack spkg (versioned by atlas) 4) make a combined package that increases in version whenever atlas or lapack gets updated. For example, linear-algebra-n.spkg where n always increases by one... Any thoughts? I've tentatively implemented option 2) in http://www.stp.dias.ie/~vbraun/Sage/spkg/atlas-3.9.32.spkg which compiles fine on F14 x86_64. The build process is definitely made simpler by including the lapack sources! But I secretly think that option 4) would be best.
