Boost.Filesystem Jamfile doesn't use the properties listed in the
error message and I don't see anything wrong with the Jamfile. My
guess is that there is some sort of a dependency from another library
that messes up these properties, but it is not clear from the message
what that other library is. Or maybe there's a different problem. A
Boost.Build magician is needed.
