It seems that no matter what I do, I keep getting a linking error with 
my latest attempt to get this to work:
/usr/local/lib/libboost_unit_test_framework.so:
   undefined reference to `init_unit_test_suite(int, char**)'

I am using boost 1.33.1.  Below is what I consider to be the relevant 
part of my code that's giving me trouble.  Most of it is copy/paste 
right out of online examples with only minor customization.  What's 
really strange is that I get another unrelated link error.  If I comment 
out my definition of init_unit_test_suite, my link errors reduce (and 
init_unit_test_suite is the only undefined symbol).  If I comment out 
the unit test code completely, the program compiles and links without 
problem.  I'm really baffled what could be going wrong.

int main(int argc, char **argv){
   ...
   boost::program_options::variables_map vm;
   ...
   if (vm.count("unit_test")){
     // code lifted from boost/test/impl/unit_test_main.ipp::main
     using namespace boost::unit_test;
     try{
       int argc_alt = 1;                      // customized
       char* argv_alt[] = {"housebot.exe"};   // customized
       framework::init( argc_alt, argv_alt ); // customized
       framework::run();
       results_reporter::make_report();
       return runtime_config::no_result_code()
        ? boost::exit_success
        : results_collector.results(
             framework::master_test_suite().p_id ).result_code();
     }
     catch( std::logic_error const& ex ) {
       std::cerr << "Boost.Test internal framework error: "
         << ex.what() << std::endl;
       return boost::exit_exception_failure;
     }
     catch( ... ) {
       std::cerr << "Boost.Test internal framework error: unknown reason"
         << std::endl;
       return boost::exit_exception_failure;
     }
   }
   ...
}

boost::unit_test::test_suite::test_suite* get_connection_test_suite();

boost::unit_test::test_suite::test_suite*
init_unit_test_suite( int, char* [] ) {
   boost::unit_test::test_suite::test_suite* test =
     get_connection_test_suite();
   return test;
