Finally, you could always try placing this in a file located at
`~/.R/Makevars`:
CC=clang
CXX=clang++
This was an 'old' workaround that ensured packages were built with `clang`
on Mavericks and above, when the transition first began...

Oh, I wonder if you have the Snow Leopard version of R installed, when you
should have the Mavericks version? What is the output of `sessionInfo()`?
You might need to install the (Mavericks, non-Snow Leopard) version of R
here: http://cran.r-project.org/bin/macosx/

says some (mangled) symbol named `__ZNSoD0Ev` could not be found. Using
the
online demangling tool at http://demangler.com/, I see this symbol is:
_std::basic_ostream<char, std::char_traits<char> >::~basic_ostream()
which should be provided by your C++ standard library.
Given that you're using `g++` on OS X, I'm assuming you installed gcc
from
macports or something like that, but either that was provided without a
standard library (libstdc++), or it's distributed in such a way that
libstdc++ isn't located on its default library search path.
So, you should either:
1. Figure out where you can get libstdc++ for the g++ compiler you've
obtained, or
2. Just use Apple's command line tools (clang etc) as that will 'just
work'.
I use install.packages(). How to clang with it?
