geoff_at_venus:~/testmake$ echo $BOOST_ROOT $LD_LIBRARY_PATH
/usr/local/include/boost-1_38 :/usr/local/cuda/lib:/usr/local/lib

Aha! I finally got it to compile correctly. Here's the resulting jamroot 
file:

--jamroot.jam--
import boost ;
boost.use-project ;
exe testmake
  : testmake.cpp
  : <library>/boost//filesystem
    <library>/boost//system
    <threading>multi
  ;

--testmake.cpp--
#include "testmake.hpp"
#include <boost/filesystem.hpp>
#include <boost/shared_ptr.hpp>
#include <iostream>

namespace fs = boost::filesystem;

int main(int argc, char* argv[])
{
   if (argc < 2) {
     std::cout << "Hello world." << std::endl;
     boost::shared_ptr<int> intPtr;
   } else {
     for (int i = 1; i < argc; ++i) {
       fs::path file = fs::path(argv[i]);
       std::cout << file.native_file_string();
       if (fs::exists(file)) {
         std::cout << " exists.";
       } else {
         std::cout << " doesn't exist.";
       }
       std::cout << std::endl;
     }
   }
   return 0;
}

Thanks for the help!
