Please use the following command line:

bjam --toolset=msvc
architecture=x86 address-model=64 runtime-link=shared link=shared

The command line you've specified say:
1. Build with 'msvc'
2. Build also with 'msvc' using address-model=64, etc

So, in essence you request two builds. The 64-bitness is presently
not represented in library name, or library path. So, you request to
create two variants, and place them in the files with the same name.
Boost.Build detects this conflict and reports its.

You might want to note that 'msvc' is shorthard for toolset=msvc,
whereas --toolset=msvc is actually same as 'toolset=msvc'. It's
unfortunate that --toolset option exists, and advertised in the
getting started docs, but that's not a topic for today.

Also note that it would be great if your configure your mail client
not to wrap long lines into unreadability :-)
