[Boost-build] two really dumb questions

I'm trying to get safe numerics tweaked to work with bjam.

First question:

I've got the Jamfile.v2 in the safe_numerics/test directory so it works 
to my satisfaction when I invoke b2 from within that same directory. 
Same goes for safe_numerics/example directory.  Now I want to run both 
Jamfiles  Based on the information from

http://www.boost.org/build/tutorial.html

I created a Jamefile.v2 which looks like this

build-project examples
build-project test
#build-project performance

and attempt to run b2 on that.  But it doesn't produce any results.  All 
I get is:

boost_root: /Users/robertramey/WorkingProjects/modular-boost
locate_root: /Users/robertramey/WorkingProjects/modular-boost
oost.org
You will need to manually configure MPI support.
...found 1 target...

Where am I going wrong here?

Second question:

 From the same tutorial it describes the song and dance that bjam goes 
through to find the Jamroot and all the installed tools. But it looks 
like that the project has to be in a subdirectory of the boost 
distribution.  And indeed, it doesn't work when moved outside the boost 
directory tree.  Is there something that I can do so the safe_numerics 
project can be placed outside of the boost super project.
