CppUnit Linking error with Clang on Mac OS X

I am trying to compile a test program using CppUnit. The problem is, with this sample code:

//[...]

class EntityComponentTest : public CppUnit::TestFixture
{
CPPUNIT_TEST_SUITE( EntityComponentTest );
CPPUNIT_TEST( testGetComponents );
CPPUNIT_TEST_SUITE_END();
Entity e;


public:
void setUp(){
    e.addComponent("1", new TestComponent("Hello 1"));
    e.addComponent("2", new TestComponent("Hello 2"));
}

void tearDown(){}

void testGetComponents()
{
    TestComponent &first = static_cast<TestComponent&>(e.getComponent("1"));
    TestComponent &second = static_cast<TestComponent&>(e.getComponent("2"));

    CPPUNIT_ASSERT(first.msg == "Hello 1");
    CPPUNIT_ASSERT(second.msg == "Hello 2");

}


};
CPPUNIT_TEST_SUITE_REGISTRATION( EntityComponentTest );
int main(void)
{
//followed from tutorial
CppUnit::TextUi::TestRunner run;
CppUnit::TestFactoryRegistry &r = CppUnit::TestFactoryRegistry::getRegistry();
run.addTest(r.makeTest());

run.run("", false, true);

return 0;
}

I am getting the linking error:

 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am using the -lcppunit flag when invoking clang. When I run the make file on my Linux machine, it compiles fine.

libcppunit-1.12.1.0.0.dylib
libcppunit-1.12.1.dylib
libcppunit.a
libcppunit.dylib

Are in my /usr/local/lib/. I even tried installing to /usr/lib and the same linking error occurs. Any help would be greatly appreciated.

Thanks very much!

EDIT: I figured out the problem. I am using libc++ since I am using std::shared_ptr in my project. Problem is that I tried compiling CppUnit with libc++ but it throws linking errors. It seems it must be compiled with libstdc++, which would require me to install Fink or Macports so I could install the latest version of gcc and libstdc++. I really hope to avoid this since there will be a whole mess trying to set it up. I really also hope to avoid using Boost for the shared_ptr.

Is any of this possible? If not I'll probably give in and install MacPorts
