I just installed boost 1.42.0 from macports using `sudo port install boost`.

Everything worked fine. Now I have a project that I'm trying to build using a makefile. Everything builds fine until it comes to the file that needs the boost library. 

It says:  

src/graph.h:20:42: error: boost/graph/adjacency\_list.hpp: No such file or directory

That file is actually located in two places:  

/opt/local/include/boost/graph/adjacency\_list.hpp  

and  

/opt/local/var/macports/software/boost/1.42.0\_0/opt/local/include/boost/graph/adjacency\_list.hpp

In the file src/graph.h where it's looking for boost/graph/adjacency\_list.hpp, the include statement is here:  

`#include<boost/graph/adjacency_list.hpp>`

How do I make this work?
