This is on an early 2008 MacPro: Quad-Core Intel Xeon (and I was getting a different error relating to osversion.) This is the oldest MacPro that El Capitan supports and I'm wondering if the next OSX version will drop it from support. > See here https://stat.ethz.ch/pipermail/r-sig-mac/2014-May/010894.html > and Simon's reply. > > I now have a computer with an i5 processor; the gfortran 4.8.2 from > r.att.research.com works without that message.

I see that now, but I instead read the Admin/Install document and thought it was specific enough to attempt a solution which fortunately succeeded. I didn't have a ~/.R/Makevars file and didn't know how it would work. I thought apparently incorrectly that such a file was designed only for environment variable settings. I got the impression that modifying Makeconf would be the preferred method. Appears I could have gone that route as well after reading Prof Ripley's posting. I would not necessarily have found that thread because I was searching on the specific error message and the original poster upthread did not include any specifics. She apparently had enough knowledge to be satisfied with "general" problems statements and the correspondingly general responses, while I'm somewhat more limited in my capacities to muck with "internals".
