I have the same problem exactly. All I could work out is that it's due
to checker.cpp including the old-fashioned iostream.h instead of
iostream. You can patch it to make it build easily enough...

... but I doubt that's a good idea.
I haven't been able to find a library anywhere on my system that exports
the symbols I get when including iostream.h. Perhaps my -current build
is incomplete for some reason.
Here's an ultra-simple test case if it helps anyone:
fornost ~/tmp % cat test.cpp

#include <iostream.h>
#else
#include <iostream>
using namespace std;
#endif
int main()
{
cout << "Hello, world." << endl;
return 0;
}

fornost ~/tmp % ./test
Hello, world.
