What parameters need to be passed to ./configure in order to avoid  
Apple's lapack/blas?

# For Apple's vecLib, I was using this

It is the first two that should be combined with your patch and the - 
ff2c options, correct?

Ben

p.s. I have a busy day. I may not have an opportunity to try your  
patch for the next 9-10 hrs.
