[Boost-build] [bbv2] propagating requirements to libraries

Sorry for the newbie-ish question, but I couldn't find the answer in the 
docs or by playing with BBv2, so ....

I have a situation like this:

project
     : requirements
       <library>/boost/test//boost_unit_test_framework
       <link>static
       # MSVC-8's iterator debugging causes some tests to run forever.
       <toolset>msvc-8.0:<define>_HAS_ITERATOR_DEBUGGING=0
     ;

test-suite "accumulators"
     : [ run count.cpp ]
       [ run covariance.cpp ]
...
     ;

This causes all of my tests to crash, because the tests are built with 
_HAS_ITERATOR_DEBUGGING=0, and the unit test framework is not. What I 
really need to do is build my *own* version of the unit test framework 
with this define, and link to that. But I don't know how to get the 
<define> requirement to propagate to the library.

Can anybody tell me the magic incantation?
