Follow-up Comment #1, bug #46499 (project octave):
I've run into this recently so it's still fresh what to do. Basically you have
to compile openblas yourself.
It's not too hard but, of course, a PITA. Download it from
http://www.openblas.net then edit the file Makefile.rule and search for "64".
You need to change a couple of things - BINARY64=64 INTERFACE64=1. Then make
and make install.
Something Julia does is provide binaries with all the dependencies included,
precompiled for generic 64 bit Linux. I think this is a neat idea - the whole
bundle is 178M unpacked. The amount of pain saved is worth duplicating the
libraries... I know, heresy to say that on Linux! ;)
