We have identified a bug in system lapack provided by the accelerate framework that prevents proper functioning of arpack. I am writing to request the addition of a new variant in installation of arpack and octave to use lapack installed from macports. Something like: $ port install octave +lapack Currently the only two variants for lapack are accelerate and atlas. Regards, Manav
