I am unable to build boost.test 1.32.0 on MacOS X 10.3/10.4.  The build fails due to some undefined symbols. 

On MacOS 10.3, these symbols are:

cpp_main(int, char**)

test_main(int, char**)

init_unit_test_suite(int, char**)

On 10.4, these symbols are

__Z8cpp_mainiPPc

__Z9test_mainiPPc

__Z20init_unit_test_suiteiPPc

Does anyone know why this is happening and how to fix it?  Thanks.  Below is the output of the first of these link errors on 10.3:
