Hmm, I forgot about --arch. As Simon said, you should be able to do it by
R --arch=x86_64 --no-multiarch CMD INSTALL
My guess is that you need --no-multiarch, but I cannot experiment with this where I sit.

Specifically this means that it will try to compile the package for all architectures, which will fail because ROOT is only installed for one of the architectures. This will happen for any package with C code you install from source, try picking your favorite R package with C code (say, preprocessCore), set options(pkgType = "source") and install it using biocLite. You will see several compilation runs.

The "gcc version 4.2.1" comes from Apple's Xcode 3.1 gcc-4.2 branch since that is what they define - it just adds Fortran support to the existing gcc 4.2.1 branch of Apple that you installed as Xcode. However, the Fortran part is merged from the GNU Fortran 4.2.4 release - hence I refer to it as 4.2.4.
