boost build v2: libraries duplicated on link line

Hi,

I just has a first go at boost build v2. It looks really good, and I 
even found every thing I needed to get going in the documentation!

I had to add .cc as a C++ file type (how would I do that without 
modifying the new/*.jam files?)

I can't seem to build my dll, however. Using my Jamfile...

all.cc = ... some C++ files... ;
lib xju : [ sequence.unique $(all.cc) ] boost_regex : <include>.. 
<include>../../boost_1_30_0 ;

lib boost_regex : : <name>boost_regex 
<search>blah/regex/build/bin/boost_regex.dll/gcc/release/runtime-link-dynamic 
;

... boost_regex.dll appears *twice* on the link command line, and the 
link fails with multiply-defined symbols.

Am I doing something wrong?
