Yes.  A quick poll of systems I have access to has svn 1.6.x on 10.7, 
1.7.x on 10.8 and 10.9.  As AFAICS it is part of Xcode, it depends on 
the version you had installed and I believe those machines were all 
fully updated.

I have

% cat config.site
CC="clang -mtune=native"
OBJC=$CC
F77="gfortran-4.2 -arch x86_64 -mtune=native"
FC=$F77
CXX="clang++ -mtune=native"
CFLAGS="-g -O2 -Wall -pedantic -Wconversion -Wno-sign-conversion"

Those are rather picky C flags, of course: intended to pick up issues 
with long vectors.

gcc/g++ are not the same as clang/clang++, although the only differences 
I have detected are what they report themselves as.  As I don't know if 
there are any material differences I chose to use clang explicitly. 
Similarly calling gfortran-4.2 explicitly to avoid any other versions 
(and I would even consider using /usr/local/bin/gfortran-4.2).

Otherwise you could select clang as your compiler: see http://cran.r-project.org/doc/manuals/r-release/R-admin.html#OS-X-packages . There are also compilers called 'gcc' and 'g++' in Xcode 5.0.1: these are clang-based but are not quite the same as clang/clang++.  Although g++ reports

The external software at http://r.research.att.com/libs/ which I know does is gdal and zeromq. It would be prudent to compile Rcpp with the same compiler as a Rcpp-using package, although not always necessary.
