Thanks to Brian for answering the above.

I think you're mixing up the terms and confusing yourself. Please read
R for Mac FAQ (at least FAQ 12.13). There are two binaries - one is
the Tiger binary with two architectures (32-bit PowerPC [ppc] and 32-
bit Intel [i386]), the other is the Leopard binary with four
architectures (32-bit PowerPC [ppc], 32-bit Intel [i386], 64-bit
PowerPC [ppc64] and 64-bit Intel [x86_64]). You can never have both
builds on one machine, because they install in exactly the same place
-- however having both makes no real sense because the Leopard binary
is functionally a superset of the Tiger binary.
Whether a given package works in 64-bit is up to the package and
dependencies in your system. Although we provide package binaries for
the Leopard build, it is not as complete, because currently we require
that a package also compiles in 64-bit for it to be included and there
are occasionally unmet dependencies. As a fallback you can usually use
a Tiger R package in the Leopard build, but it is not something we
guarantee and will give you 32-bit only.
One important note: if you have installed one build over the other,
unexpected things can happen since this is not meant to work. It is
highly advisable to start from scratch before switching between Tiger
and Leopard build, e.g.
rm -rf /Library/Frameworks/R.framework

Note that GUIs are specific to both the build and 32/64-bit --- as you
can see on the nightly page there are three different GUIs: tiger-
Deployment (32-bit Tiger build), leopard-Leopard (32-bit Leopard
build) and leopard-Leopard64 (64-bit Leopard build). You have to use
the GUI(s) that matches your installation. If you installed R from the
Installer packages (CRAN or R-2.8-branch-leopard.pkg), you will have
the correct GUIs in Applications.
I hope his helps,
