I am sorry - I am confused and am trying to find my way out:

*- What is listed for download on sourceforge does not reference a
version of build v1 or bjam v1 or what have you. ( I am confused as to
how to get the older version)

* when I build the code in jam_src and run it- it reports:
Boost.Jam  Version 3.1.8. OS=NT. 
        This is the same version I used to build boost with
(successfully) with vc7.1. I am using the source for bjam included in
the 1.31 release of boost

* when I try to build boost with a simple bjam stage at the root dir of
boost, it succeeds

* when I double check the BOOST_ROOT env var with a dir command- it
shows me the right dir

* my TOOLS envvar is set to TOOLS=vc7.1
        This was necessary before being able to build boost

* when I CD into the HELLO example for bjam and try a 

        Bjam

        I GET

        warning: no toolsets are configured.

When I TRY:

bjam -sTOOLS=vc7.1
bjam "-sTOOLS=vc7.1"
bjam  debug
bjam release
bjam "-sTOOLS=vc7.1" debug
bjam "-sTOOLS=vc7.1" release

I always get the above errors

If I COPY the files in \tools\build\v2\example\hello to the ROOT of
boost (and overwrite the jam file there)- IT DOES BUILD PROPERLY

I have build bjam and stepped through it in the IDE and was not able to
make much of what the source was doing (other than it looks like a lot
of recursive parsing of files) (spent most of my evening yesterday doing
that.

MY QUESTIONS:

* Which is the right version of boost to be running here? 
* does the \tools\build\v2\example\hello sample bjam compile for anyone
else? (i.e. is it broken?)
* is there a good sample of a simple working example for bjam somewhere
else?
* Any ideas on why I can BUILD BOOST but not any of the subprojects
(everything else I have tried has the same problems)
* How do you folks debug this thing- ****any**** techniques would be
helpful
* is the toolsets it is complaining about the COMPILER (i.e. TOOLS
envvar?) or is it something else entirely?
* HELP ! :) 

I am doing this pain because I am trying to get boost defined as the
standard in my company (It is within my power to do that). I would also
like to use the bjam tool as our standard build tool, but I FIRST need
to figure out how to build projects with it (grin).

Thanks to anyone for thoughts or things to try.

Thanks
