Yes for sure - take a look at the readme.txt file in the root of the 
sandbox, which reads:

    "This directory contains the file "boost-build.jam" which search for a 
Boost install as follows:

   * In a directory specified by the --boost=path command line option.
   * In a directory specified by the BOOST environment variable.
   * In the directories ../boost and ../Trunk.

   In addition the variables BOOST and BOOST_ROOT are set to point to the 
root of the Boost install, so to refer to other
   Boost libraries and the main Boost headers, your Jamfile should contain 
something like:

   import modules ;

   local boost-path = [ modules.peek : BOOST ] ;

   And then you can refer to a Boost library "foo" as:

   $(boost)/libs/foo/build//boost_foo

   Note that if your project does not specify a Jamroot file, then a default 
one is provided for you,
   and that this file will automatically add $(BOOST)/ to your include 
path."

In other words the machinery in the root directory of the sandbox will take 
care of almost everything for you - all you need to do is set the BOOST 
environment variable - and then add the local include path (to your sandbox 
headers) to your projects requirements.

Couldn't be easier... honest... John ;-)
