New description:

 Due to the following code in boost/config/stdlib/libstdcpp3.hpp
 BOOST_NO_CXX11_SMART_PTR (among other things) is getting defined for clang
 3.4.2 built with gcc-4.8.2 on CentOS 7.  Apparently clang 3.4.2 defines
 __GNUC__ as 4 and __GNUC_MINOR__ as 2.

 The net effect is that no get_pointer is defined for std::shared_ptr and
 boost::binds break down.
