[Boost-build] Want libraries output to specified location with appending "/lib"

How can I tell boost to put the libraries in a directory that I specify? 
If I change stage-dir, it still appends /lib onto it. Is this possible?

I want my libraries in C:\trunk\third_party\
Not in C:\trunk\third_party\lib

Here is my build script:

cd ..\boost
SET PATH=$(PATH);..\bjam
bjam.exe --stagedir=../../third_party --with-thread toolset=msvc-9.0 
link=static threading=multi runtime-link=shared variant=debug stage
bjam.exe --stagedir=../../third_party --with-date_time toolset=msvc-9.0 
link=static threading=multi runtime-link=shared variant=debug stage
bjam.exe --stagedir=../../third_party --with-system toolset=msvc-9.0 
link=static threading=multi runtime-link=shared variant=debug stage
bjam.exe --stagedir=../../third_party --with-regex toolset=msvc-9.0 
link=static threading=multi runtime-link=shared variant=debug stage
bjam.exe --stagedir=../../third_party --with-program_options 
toolset=msvc-9.0 link=static threading=multi runtime-link=shared 
variant=debug stage
bjam.exe --stagedir=../../third_party --with-filesystem toolset=msvc-9.0 
link=static threading=multi runtime-link=shared variant=debug stage
