Yeah, that clearly would happen, so the boost-cmake build won't let you 
proceed until you confirm that you understand the system is 
experimental.  It looks like this:

% cmake ../src

CMake Error at CMakeLists.txt:54 (message):

-- Configuring done
of course we can tweak the message as necessary.  Maybe it should 
mention specifically to keep cmake chatter off of the main boost list.

Yeah, as rigorously as one could given our resources (small)

Sure...  just build boost with it.
