[boost] [1.56] Sorry but no PDF doc build (build script has been broken)

Sorry folks, but as things stand there will be no PDF build of the docs for 1.56 as the build script appears to be hopelessly broken :-( Each time I fix one Boost.Build error it just leads to another, and frankly at present I have neither time nor inclination to keep tracking these down. If anyone wants to experience some pain then trying to invoke bjam in /doc/pdf/ will give you an idea of some of the issues. Regards, John.
