Thanks for the link! I don't have the OP's issue with the missing fortran libs, but further down someone reports having the EXACT same issue I have: https://groups.google.com/d/msg/sage-devel/zQsZsivts0I/cblwvEkNDgAJ
I posted on sage-devel about this and left a copy of the relevant logs. Anyway, it seems that setting OPENBLAS_CONFIGURE="TARGET=ATOM" resolved this issue, so I am going to try this later today. :-) One thing I am confused by is the setting ATOM itself. I have a Celeron, not an Atom processor. Is this just a catch-all setting for lower-end cpus?
