Well I have uploaded version 1.34.1 and the function is declared as

     explicit thread(const function0<void>& threadfunc);

and defined as

thread::thread(const function0<void>& threadfunc)
     : m_joinable(true)
{...}

and used in

thread* thread_group::create_thread(const function0<void>& threadfunc)
{
.
     std::auto_ptr<thread> thrd(new thread(threadfunc));

I don't see where is the error? Does 
libboost_thread-gcc34-mt-p-1_34_1.so defines thread_group::create_thread ?

Best,
Vicente
