It sounds like you have a partial version of Boost 1.27.0, because the
is_stateless trait is in 1.27.0. You can try a partial updates using the
web-based CVS, but anything more than a small update is quite tedious.
First go to the browseable CVS repository at:

  http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/boost/

You can navigate to boost/boost/type_traits, and then click on the
"object_traits.hpp" header file (where is_stateless is located). Then you
can look for the version that says: CVS Tags: Version_1_27_0, RC_1_27_0 

Click "view" to see this version of the source code, and you can save it
locally.

I would still advise you to get the Boost 1.27.0 tarball again and unpack
it instead of going through all of this hassle.
