[boost] my code -> utility -> type_traits -> mpl -> ERROR

Hi all,

why does boost/type_traits/detail/bool_trait_def.hpp include
boost/mpl/bool.hpp ??

which means I get a link  ERROR: Undefined symbol:
boost::mpl::bool_<0>::value

in code that seemingly nowhere includes anything near MPL (on AIX 433 with
xlc6 and STLport), but merely mortal stuff like boost/shared_ptr or
boost/utility.

o, I forgot, utility passes type_traits passes, well, mpl.

Yes I tried, utility_fwd where applicable and also outcommenting some stuff
in utility.hpp and No I do think everything will work at once.But I do no
understand why I have to suffer from this from my point of view uneccesary
dependancy. 

Can anyone please help? Or give me a pointer say "USE_THIS_HELPFULL_MACRO"?

Thanks in advance..

(MPL http://www.boost.org/libs/mpl/doc/index.html#details.depend mentions it
depends ON the type_traits lib, and not the other way around, if both -
isn't this circular?)
