That's because some time ago, someone comitted the following:

2003-05-26 16:56 vladimir_prus

* project.jam: Refactorings: remove 'project-root' attribute of
project, for lack of any use.

* new/project.jam (initialize): Register with project root here.
Don't initialize the 'project-root' attribute.
(project-attributes.set): Don't allow 'project-root' and
'project-root-module'.

Well... there was some use of the removed stuff. That someone is now writing a 
testcase and fixing the problem you see... done. The updated new/project.jam 
will be in anonymous CVS withing 24 hours, at 
http://boost-consulting.com/boost/tools/build/new/ withing hour and at
http://zigzag.cs.msu.su:7813/~ghost/working_copy/new/ 
right now.

Note that 'get-location' returns relative path. The following will be needed 
to get absolute one:

import path : root pwd ;

local l = [ project-root get-location ] ;
ECHO [ root $(l) [ pwd ] ] ;
