Hi,
thanks Volodya, that actually gets me a step further.
Unfortunately I'm still not there yet ;-), see below.

Is this an environment var? Please read:
No, not an environment variable, it is set on the command line
using '-s' option.  Is this still supported in v2?
It's considered

No. In V1, top-level dir had to have Jamfile+Jamrules. In V2,
top-level dir
should have Jamroot.
Ok, so I've replaced Jamfile+Jamrules with the following files:

boost-build ../../../boost/tools/build/v2 ;

<Jamroot>
using msvc : 8.0 ;
BOOST_LOCAL_STAGE_DIR ?= stage ;
rule Pseudo ( target : libname : libtype : variant )
{
        VARIANT = $(variant) ;
        NOTFILE $(target) ;
        DEPENDS $(target) :
        $(BOOST_LOCAL_STAGE_DIR)/$(libtype)/$(libname)/$(variant) ; stage
        $(BOOST_LOCAL_STAGE_DIR)/$(libtype)/$(libname)/$(variant)
Uh, oh. I did not even notice you're using those low-level tricks. I'd suggest using:

        stage $(target)
                : <sources>
                : <location>$(BOOST_LOCAL_STAGE_DIR)/$(libtype)/$(libname)/$(variant)
                  ...........

and removing NOTFILE and DEPENDS completely.
