[R-SIG-Mac] R 4.5.0 and veclib version of blas

[roy]

After executing the following:
cd /Library/Frameworks/R.framework/Resources/lib
ln -sf libRblas.vecLib.dylib libRblas.dylib

Running R (4.5.0) produced a warning (stats not found) and then sessionInfo
failed.  See below.  When I switch back to the R version of blas all worked
well.

I saw this problem on macos 15.4.1 for both intel and m2.

cheers, roy
