Hate to ask this, but are you really, really sure?

Does the above actually work, or are you leaving something out? I don't know
if boost-build.jam is subject to some special treatment but you'd normally
need to e.g.:

local ARGV = [ modules.peek : ARGV ] ;
local BOOST_ROOT = [ modules.peek : BOOST_ROOT ] ; # or use "os.environ"

Sorry, that's all I can see. Haven't used bjam/ more recent than
1.40 a lot, so I haven't seen any similar problems.
