I wanted to follow up on this thread from a few months ago about BLAS
options in the current R package.

Simon, is it possible to go forward with one of the following two options?

1) leave libRblas.vecLib.dylib out of the R package (AFAIK this is how
things currently stand in the 3.0.2 pkg) but update this FAQ (
http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html#Which-BLAS-is-used-and-how-can-it-be-changed_003f)
to tell folks that they can enable vecLib BLAS by symlinking the Accelerate
framework as:

cd /Library/Frameworks/R.framework/Versions/Current/Resources/lib
ln -s
 /System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib
libRblas.dylib

1a) Our systems administrator here suggested the additional possibility of
have the R installer have an option (perhaps under the Customize button at
the point where "Installation Type" is chosen) that the user could select
to have switching to vecLib be done as part of the install.

2) Return libRblas.vecLib.dylib to the R package, in which case the current
FAQ will then be accurate.
