You are using libstdc++ as your standard library. It needs to be 
patched [1] to work with clang. Otherwise you can use libc++ [2]
as your standard library which works out of the box with clang.

Note that the patch I linked to is against libstdc++ from gcc 4.7.
It may or may not work with your libstdc++, which appears to be
from gcc 4.6 (at the least you may have to apply the patch 
manually, which isn't a big deal as it's just one line).
