[boost] how to build boost with bzip2 in non-standard location?

Hello, I want to build the full boost library, while I don't have bzip2 installed system-wide (but I just downloaded and installed it locally). It seems to me that http://www.boost.org/boost-build2/doc/html/bbv2/tasks/libraries.html should be relevant here for that task, but I find the descriptions too general to understand. I wonder whether somebody could simply tell me the lines to be entered into the bjam-configuration file? Perhaps bz2 : : <file> Path_to_libbz2.a ; But how to specify where to find bzlib.h ? Isn't it possible to specify the base directory, where then, as, usual include, lib and bin are found? Thanks in any case! Oliver
