You can try this:

curl http://r.research.att.com/R-25-br-quad.tar.gz -O
tar fvxz R-25-br-quad.tar.gz -C /

It is a quad-arch framework (including 64-bit x86). To run the 64-bit  
version, use
/Library/Frameworks/R.framework/Resources/bin/R64

If you want to use X11, you'll need 64-bit client in /usr/local/X11R7  
(I used Xorg).

There are two possibilities:
1) use --without-iconv (untested)
2) get 64-bit iconv:
   a) compile it from Apple's sources
     or
   b)
curl http://r.research.att.com/libiconv.2.dylib -o /tmp/libiconv. 
2.dylib \
&& sudo cp /tmp/libiconv.2.dylib /usr/lib/libiconv.2.dylib

It is strange, because Xcode SDK contains 64-bit stub for iconv, but  
the system library is 32-bit only.

I'm not sure I can comment on this using a public mailing list, so  
all I'll say is that the hot fix is to apply this patch to src/ 
include/Rinternals.h:

I didn't test this in 2.5 yet, but I think you get the idea.
