Unfortunately bcp isn't smart enough to not look into optional dependencies 
that are guarded by #ifdef. In this particular case it follows the 
dependency to detail/quick_allocator.hpp, which in turn brings in the 
type_traits and mpl libraries. But quick_allocator.hpp is only used if you 
#define BOOST_SP_USE_QUICK_ALLOCATOR.

The only reliable way that I know of is to copy the required headers into a 
pristine include directory one by one until your program compiles. Not 
particularly elegant, but it works. In shared_ptr's case you need

boost/assert.hpp
boost/current_function.hpp
boost/checked_delete.hpp
boost/throw_exception.hpp

Most of boost/detail/, so I just copy it wholesale
boost/config/*
