Xcode was released last week, although it did not show up as an update
for me until this. It may be available only for Mountain Lion: the
command-line tools seems only to be.
As expected, the compilers used for the CRAN binary build, llvm-gcc-4.2
and llvm-g++-4.2, are not part of Xcode 5. Less expected was that
updating to Xcode 5 did not remove them, at least for me.
All that is needed to build R or install packages is the 'Command-line
tools for Xcode' These can be downloaded from
https://developer.apple.com/downloads/index.action (registering your
Apple ID for that site is needed). New users could download and install
Command-line tools (OS X Mountain Lion) for Xcode (April 2013)
Command-line tools (OS X Mountain Lion) for Xcode (September 2013)
and install them in that order.
We have been testing building R and packages with clang since R 3.0.0,
and details of how to do so are in the 'R Installation and
Administration Manual'. Xcode 5 updates to
tystie% clang --version
Apple LLVM version 5.0 (clang-500.2.75) (based on LLVM 3.3svn)
whatever '3.3svn' means (3.2svn meant 3.1+epsilon).
