[Dakota-users] Cannot find BLAS library compiling DAKOTA for Mac OS X

[Doug Reeder]

Paul,

I have found it difficult to pass the framework information. I would  
try to just edit the Makefile to point to the right places, but I  
think that configure fails so that you don't get a Makefile. Can you  
point configure at a non-apple set of lapack and blas (you can  
download them and build them w/ gfortran or ifort), just to get  
through the configure step, and then edit the Makefile to point to  
the framework.
