I agree with John. I'd be much better if boost
provided a clear description on how to build the
library manually. I am having a bunch of problems with
automatic boost builds especially when they include
dlls.  I also think that exporting C++ classes is a
broken concept too. It is even worse than the
automatic builds. Just my $0,02
