Other than defining BOOST_FILESYSTEM_VERSION as 3, you shouldn't have
to do anything special.

Let's concentrate on Linux rather than the Mac, since I've got Ubuntu
running under VirtualBox here.

First, some basics:

* What version of GCC are you running?

* Are you running Boost 1.44 or svn trunk?

* How are you building? Are you using bjam?

* If you cd to libs/filesystem/test, and run "bjam" (without any
arguments), what happens?
