[Boost-users] thread and Mac OS X

i've written a little test to see if i've installed boost properly on my mac

#include <boost/thread.hpp>
#include <boost/shared_ptr.hpp>
#include <boost/bind.hpp>

#include <iostream>

void simple_thread( boost::shared_ptr<int> p )
{
        std::cout << (*p) << std::endl;
}

int main (int argc, char * const argv[]) {
 
        boost::thread_group threads;
        for ( int i = 0 ; i < 5 ; i++ )
        {
                boost::shared_ptr<int> p( new int(i) );
                threads.create_thread( boost::bind( &simple_thread, p ) );
        }
        
        threads.join_all( );
        
        return 0;
}

in xcode (a C++ Tool project) this compiles fine, however on runtime i
get the following error:
ZeroLink: unknown symbol '__ZN5boost12thread_groupC1Ev'
boost_test has exited due to signal 6 (SIGABRT).

using g++ i get the following errors (ignoring warnings)
g++ main.cpp -o boost_test -I/usr/local/include/boost-1_31 -L/usr/local/lib
 ld: Undefined symbols:
 boost::thread_group::create_thread(boost::function0<void,
std::allocator<boost::function_base> > const&)
 boost::thread_group::join_all()
 boost::thread_group::thread_group[in-charge]()
 boost::thread_group::~thread_group [in-charge]()

i originally built boost using the command line
sudo bjam -sTOOLS=darwin install

can anyone help me with what i am missing here?

thanks
