Problem went away with this command line:

bjam iostreams toolset=msvc-9.0 variant=debug,release link=static,shared 
-sHAS_ZLIB=1 -sHAS_BZIP2=1 -sZLIB_INCLUDE=D:/nan/compress 
ion/zlib/zlib123-dll/include 
-sZLIB_LIBPATH=D:/nan/compression/zlib/zlib123-dll/lib 
-sZLIB_SOURCE=D:/nan/compression/zlib/zlib-1.2.3 
-sBZIP2_INCLUDE=D:/nan/compression/bz2/bzip2-1.0.5 
-sBZIP2_LIBPATH=D:/nan/compression/bz2/bzip2-1.0.5 
-sBZIP2_SOURCE=D:/nan/compression/bz2/bzip2-1.0.5 stage

Maybe the explicit calls to variant and link forced a missing lib to be 
built.

Thanks for your help.
