[Boost-users] can't get first example in boost tutorial to work

I'm trying to install boost on mac osx 10.4.7.  I followed 
the tutorial "Getting Started on Unix Variants" found here:

http://www.boost.org/doc/libs/1_35_0/
more/getting_started/unix-variants.html

Following the instructions in the tutorial, I installed
boost in /usr/local as instructed, so my directory 
structure is:

/usr/local/boost_1_34_1/boost

But when I run the first example in the tutorial:

#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
  using namespace boost::lambda;
  typedef std::istream_iterator<int> in;
        
  std::for_each(in(std::cin), in(), std::cout << (_1 * 3) << " " );
}

I get the error(among others):

error: boost/lambda/lambda.hpp: No such file or directory

If I change the include path to:

#include </user/local/boost_1_34_1/boost/lambda/lambda.hpp>

I get the error(among others):

error: boost/lambda/core.hpp: No such file or directory

But core.hpp is in the lambda directory:

/usr/local/boost_1_34_1/boost/lambda$ ls     
algorithm.hpp           control_structures.hpp  lambda.hpp
bind.hpp                core.hpp                loops.hpp
casts.hpp               detail                  numeric.hpp
closures.hpp            exceptions.hpp          switch.hpp
construct.hpp           if.hpp

I'm using the Xcode 2.4 IDE to run my C++ programs.

I also tried to execute the program from the command line with
the original include path:

#include <boost/lambda/lambda.hpp>

but I get the same error:

~/2testing/dir1$ g++ prog1.cpp
prog1.cpp:1:35: error: boost/lambda/lambda.hpp:

prog1.cpp: In function 'int main()':

prog1.cpp:8: error: expected namespace-name before ';' token
prog1.cpp:8: error: '<type error>' is not a namespace
prog1.cpp:11: error: '_1' was not declared in this scope

I get the same errors again with the full include path:

#include </user/local/boost_1_34_1/boost/lambda/lambda.hpp>

$ g++ prog1.cpp
In file included from prog1.cpp:1:

What path should I be using?  Or, should I set an environment variable somewhere?
