build setup - what have I missed?

This worked once.  Then the [yeah, it wasn't backed up] disk drive died.
Target system is Win2000, SP5 and MS Visual C++ 6.0, SP5.

Downloaded boost-build.win.zip and extracted it to c:\bin\boost-build.
Added c:\bin\boost-build to the path.
Set environment variables:
      BOOST_BUILD=c:\bin\boost-build
      JAM_TOOLSET=VISUALC
      VISUALC="c:\Program Files\Microsoft Visual Studio\VC98\bin"

Checked out  from CVS to d:\dev

cd'd to d:\dev\boost and executed:
%BOOST_BUILD%\jam -sBOOST_ROOT=. -sTOOLS=msvc

<result>
warning: unknown rule boost-build
don't know how to make all
...found 1 target...
...can't find 1 target...
</result>

I've clearly screwed something up but I can't figure out what.  Help would
be appreciated.

TIA (from the eternal newbie)
