Is --with-blas="-lgoto2" a known problem (other than possibly not being the preferred choice)?
And what precisely is it? And what chipset are you using?
I thought I had been testing RC with the same setup I regularly use, but I now see there was a slight difference. I am now getting the following failure in make check on 32-bit Ubuntu 12.04, configuring with --with-blas="-lgoto2". (These may not be surprising statistically or numerically, but it is a bit disconcerting when make check fails.)
No failure shown here ... surely you know that the signs of principal components are not determined?
And 32-bit platforms seem prone to round in different ways (to each other and to 64-bit platforms): the differences in the last digit are typical of 32-bit platforms.
