In your Jamfile.v2, you have:  "$(BOOST_ROOT)//filesystem"  Is
BOOST_ROOT actually defined?  You can add the line "ECHO $(BOOST_ROOT)
;" to your file to find out.  If it's not, then those lines will expand
to nothing.

In my setup, boost's Jamfile.v2 sets up the libraries as
"/boost/thread", "/boost/filesystem" and I just use those (note: no
"//").  On the other hand, I've got boost as part of my source tree
(under the directory containing Jamroot.jam) instead of outside it, so
that may make a difference.
