In fact, I'm trying this on a mostly stable system which resulted in the
very old =sci-libs/cblas-reference-20030223-r4 being pulled in.  I used
the autounmask feature of portage which did not spot the resolution of
this conflict: (unmasking sci-libs/cblas-reference-20110218 from
science).

Neither.  In in the process of building now.
