Yes.
1. Tell me what system is this. Is this NT, or (as I suspect) cygwin/mingw.
Try this:

$bjam -f-
ECHO $(OS) ;
<Ctrl-D> or <Ctrl-Z> (depending on shell)

2. Go to E:/libs/boost/tools/build/v2/tools\stage.jam:359
and add 
ECHO "NT!" ;
and 
ECHO "Not NT!" ;
to both branches of the 

if [ $(property-set).get <os> ] = NT

conditional.

3. Try the attached patch, or replace stage.jam with that at:
http://zigzag.cs.msu.su/~ghost/stage.jam

and tell if the problem is still there.
