Comment (by kencu):

 Yes, true. I actually have this all sorted out, but just have been too
 distracted with all the other things going on.

 The YONAH processor specified in the Portfile will not work on any 64bit
 OS, as YONAH is 32 bit only.

 So if I manually change the processor to CORE2, or let the software work
 out the processor, it builds.

 So -- this was a bug in OpenBLAS, and then our forcing YONAH is just not
 going to work. I have a fancier fix coming, using `sysctl` and testing for
 a 64-bit capable processor (and if so, forcing CORE2) but in truth,
 recreating all the OpenBLAS logic to sort out the processor in Portfile
 logic is a bit of a pain.
