If you are using Visual Studio you need to have the Boost library path you are 
using referenced correctly in
 
Project>Properties>Configuration Properties>C/C++>General>Additional Include 
Directories

and

Project>Properties>Configuration Properties>Linker>General>Additional Library 
Directories

have you done this yet?
