[Boost-build] [bjam v2] use of bjam in foreign trees]

From: Jeffrey Holle (jeffreyholle_at_[hidden])

Note: I previously attempted to send this to 
"gmane.comp.lib.boost.build" and "gmane.comp.lib.boost.user" with 
errors, message wasn't accepted.

I have moved from Mandrake Linux to Ubuntu Linux.
With Mandrake, I used boost 1.32.0 and employed bjam successfully in a
foreign directory tree.

Now, with Ubuntu running bjam from a foreign directory isn't working.
I've installed boost 1_33_1 and defined:
   BOOST_ROOT=/home/jholle/boost_1_33_1
   BOOST_BUILD_PATH=/home/jholle/boost_1_33_1/tools/build/v2

I also have a project-root.jam file in my root project directory with
this contents:
   path-constant BOOST_ROOT : . ;

I have commented out the "using gcc ;" line in user-config.jam, because
I'm using gcc (4.0.1).

The jamfile that I'm trying to use is taken from
$BOOST_ROOT/libs/multi_index/example, slightly modified.
I've alternately trying the first active line in this Jamfile to be:
   * subproject testMultiIndex ;
   * project testMultiIndex ;
   * exe basic (without either "subproject" or "project")

When bjam is run against this file, I get these errors:

What am I doing wrong?
