Added BLAS support for Vv. Ran on a small basis fine, but having problems with three concurrent runs and using gprof at the same
time on Toby; maybe a memory leak or gprof ate all the memory? The normal runs got stuck at ~9:45pm on Apr 23rd at about 7200 Lanczos iterations.
This is about 30 min after the runs were started.
