That was it! Compiling without "-f66" yields a working set of LAPACK + BLAS.
Now I have to find out why we were using that -f66 flag in our Cactus compilations. It's not a flag I'd use in any standalone code.
Thanks, Erik, for spending time on this,
Bernard

I was not able to reproduce the problem.
The option -f66 may be the culprit. It changes the semantics of DO loop so that they are executed at least once, even if the upper bound is less than the lower bound. Can you try without?
Are you using this option both within Cactus and when building LAPACK/BLAS stand-alone?
