Dear Maintainer,<br>
<br>
I installed clang-3.7 (llvm-3.7-dev), libc++-dev and libc++abi-dev in my pbuilder.<br>
When I tried to compile package libitpp [1] in chroot manually, I met a error.<br>

It seems that there is no __cxxabi_config.h in /usr/include/c++/v1 directory.<br>
So I just put a __cxxabi_config.h taken from internet in /usr/include/c++/v1, it did work then.<br>
