barry-0.18.4-shared_ptr.patch

With -std=c++-11 shared_ptr is available in the standard library so pulling in
the std::tr1 namespace creates an ambiguous reference.  Simple fix is to stop
doing that but isn't backwards compatible.  We don't care in Gentoo since we'll
always be building barry with -std=c++11 due to libsigc++ abi compatibility.
