Sam,

Your example (well, if I fill in the missing details like
BOOST_PYTHON_MODULE, etc.) works fine with the current Boost CVS and
MSVC 6.5 for me.  I bet you haven't really reduced this to a minimal
example, have you?  I'm fairly certain you'll find your bug if you do
that.  The Jamfile I used to test it was:

-------
subproject libs/python/user ;

# bring in the rules for python
SEARCH on python.jam = $(BOOST_BUILD_PATH) ;
include python.jam ;

extension foo_ext : foo.cpp <include> ../../.. ;
boost-python-runtest foo : foo.py <pyd> foo_ext ;
------

I placed it in a subdirectory "user" of $BOOST_ROOT/libs/python along
with the enclosed:
