When trying to compile the latest version of LLVM on Mac OS X 10.8.5 I get the following error/warning about libstdc++ version:

===
checking whether Clang will select a modern C++ standard library... no
configure: error:
We detected a missing feature in the standard C++ library that was known to be
missing in libstdc++4.6 and implemented in libstdc++4.7. There are numerous
C++11 problems with 4.6's library, and we don't support GCCs or libstdc++ older
than 4.7. You will need to update your system and ensure Clang uses the newer
standard library.


===

I can't find any clear info on how to update libstdc++. A similar post that I found didn't help.

Would updating libstdc++ end up breaking lots of other things?

In case it's relevant, I have homebrew installed and would like to avoid macports.

Turns out i didn't need have to explore macports for working around this issue. Mac-OSX 10.8 already has libc++ installed and llvm can be asked to use libc++ instead of libstdc++ by using the enable-libcpp flag in the configure stage.
