I use this in my user-config.jam file:

using clang
 : : :
   <cxxflags>"-I/usr/include/c++/4.5/x86_64-linux-gnu/
-I/usr/include/x86_64-linux-gnu/"
 ;

I've not spent any time figuring if this is a Boost.Build bug or a clang
configuration bug, but the above has worked well for me with clang / llvm
trunk.

Cheers,
Darren
