It was not committed yet. I've a bit improved it (nice indents) and committed 
now. Just add --debug-building option to bjam.

I wonder if it's caused by this:

feature.compose <parallelism>fake : 
<library>$(CVSTOP)/fake_mpi//libfake_mpi/<parallelism>none ;

CVSTOP = [ modules.peek : CVSTOP ] ;

You use CVSTOP before definition. If I use:

feature.compose <parallelism>fake : <library>/femtown//fake_mpi ;
lib fake_mpi ;

the application links to fake_mpi. (Somehow it links to it twice, but that's 
another thing. I'll look into it)
