-------------------------------------------------

are these the relevant paths?

  /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/include/g++-v4
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/include/g++-v4/x86_64-pc- 
linux-gnu
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/include/g++-v4/backward
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/include
  /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/include-fixed

How do I tell clang where these live?
