[Boost-build] really dumb boost build question

I'm trying to get boost build to build the serialization library for my 
msvc system under cygwin.  That is, I use the Cygwin shell on my windows 
machine and I want to build libraries and run tests.

So  I'm using the following command line

b2 --dump-tests toolset msvc link=shared test_binary_xml_archive >b2.log

Which does what I expect - that is it invokes the vc 9.0 compiler which 
is on the machine.  But compile fails because it can't find the boost 
header libraries.  The compilation fails with:

boost/config.hpp - no such file or directory.

I've verified that that the file exists.  I don't know if it matters but 
I've got BOOST_ROOT set to the c:\modular-boost directory.  In the past 
as I recall, this always "just worked".  Any suggestions appreciated.
