I should have been careful in my statement about what worked for me. I am trying to understand the problem you referred to about octave 4.0.0 not building on clang++.
I have been quite impressed with the performance of Octave code on Mac OSX using fink. My tests used octave382-atlas-qtmac 3.8.2-6. It has also been quite reliable. The fact that the code works much faster on four year old hardware with a lot fewer cpu cores and even after using the latest Ubuntu tools / libraries on the high end Intel machines on EC2 is remarkable. Apple does claim that its Accelerate framework is much faster than standard BLAS / ATLAS. A lot of the improvements were part of 10.9 / 10.10 update (see WWDC 2013-2014 videos). I will check if the default "octave" performs faster than the octave-atlas version. Now, as you imply in your last email, if the default "octave" variant uses clang already, what is the issue with octave 4.0.0 and clang++? Or is it a new issue in octave 4.0.0 in moving from 3.8.2?
