That didn't work, but your idea gave me a hint to look at Getting 
Started re bjam's defaults... then I tried the handy --debug-building 
and --debug-configuration which report concisely, and I see this:

        notice: iostreams: not using zlib compression

and in
        libs\iostreams\build\Jamfile.v2
I see:
     if [ os.name ] = NT && ! $($(LIB)_SOURCE) && ! $($(LIB)_INCLUDE)
     {
         if $(debug)
         {
             ECHO "notice: iostreams: not using $(library-name) 
compression " ;
         }
         NO_$(LIB) = 1 ;

I'm not sure what this means, but apparently it's unhappy with how I 
told it the source locations, which was:

bjam iostreams toolset=msvc-9.0
-sHAS_ZLIB=1
-sHAS_BZIP2=1
-sNO_COMPRESSION=0
-sNO_BZIP2=0
-sNO_ZLIB=0
-sZLIB_INCLUDE=D:/nan/compression/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

I tried modifying Jamfile.v2 to print more information by adding these 
lines:
     if [ os.name ] = NT && ! $($(LIB)_SOURCE) && ! $($(LIB)_INCLUDE)
     {
         if $(debug)
         {
             #new line
            ECHO "source of [$(LIB)_SOURCE]: $($(LIB)_SOURCE) " ;
             #new line
            ECHO "include of [$(LIB)_INCLUDE]: $($(LIB)_INCLUDE) " ;
             ECHO "notice: iostreams: not using $(library-name) 
compression " ;
         }
         NO_$(LIB) = 1 ;

But these don't seem to be printed... any idea what's wrong with that 
way of debugging a jamfile?
