output streams not working with units

Compiling the temperature.cpp example problems fails with this error message

S896822:example kbelco$ icpc -g -I ../../.. temperature.cpp ../../../boost/units/io.hpp(967): error: more than one instance of overloaded function "boost::units::detail::do_print_prefixed" matches the argument list:

The same message occurs with a small reproducer.

int main(int, char ) {

using namespace boost::units; quantity<fahrenheit::temperature> t; cout << t << endl; return 0;

Closing this ticket as Intel will not fix for Leopard (10.5.x) and Xcode 3.1.x incompatibility.
