I just changed boost-build.jam at the top level to set BOOST_ROOT
unconditionally, overriding any setting in the environment.

It's because you don't have the MSVC toolset set up properly, and it's
trying to guess what to do. It makes the wrong guess on your system. We're
working on instructions for all the toolsets, but we don't have any for
that one yet. There are two basic ways to set it up:

1. Run VCVARS32.bat yourself before building
2. Set MSVC_ROOT to point at your installation's VC98 directory

HTH,
Dave

**Future versions of Boost.Jam will have the ability to look in the Windows
registry so it doesn't have to guess.
