[boost] [locale] trouble building

I grabbed the ICU bin for VS2010. I extracted the content into d:\icu so that d:\icu\include has the various includes. I set up the PATH variable to include d:\icu\bin... I copied boost and lib from the review into boost_1_46_1 where the root of boost source is. The docs seem to imply that I can get a build without ICU if I'm using Windows but this doesn't seem to be the case. I tried --without-icu and I got an error about using --with and --without for the same lib. Here's my attempt to build (with ICU installed): D:\boost_1_46_1\boost_1_46_1>bjam --build-dir=.\build toolset=msvc-10 --with-loc ale --prefix=d:\boost_msvc_1461 --layout=system -sICU_PATH=d:\icu
