It appears to me that you are building on some kind of a network filesystem and timestamps are getting messed up. Can you build in /tmp or somewhere, which may be guaranteed to have local storage and hence avoid these clock issues?
If still doesn’t work, I will create some binaries and upload and put up all the instructions. Since openblas still has some issues to be fixed on power, I am using an ATLAS build (of which we are using the latest RC), and packaging it all up is going to be some work. -viral > On Jul 22, 2016, at 1:50 PM, Paulito Palmes <ppal...@gmail.com> wrote: > > This problem might be specific to Redhat?
