Hi,
I've just comitted a number of changes to project.jam/os.path.jam. In effect 
they:
1. Switch to using relative project locations
2. Finally make "project-test1.py" work.

Here's the procedure I've tried
1. Make a fresh checkout
2. Build jam
3. Copy "new/boost-build.jam" to "test"
4. Cd to "test"
5. Set BOOST_BUILD_PATH to "../new" 
6. Run "project-test1.py"
7. Watch "PASSED" printed.

A couple of questions

1. We already look for jam relatively to the test dir. Should we set 
"BOOST_BUILD_PATH" automatically as well, so that we don't pick any 
declaration in the environment?

2. Rene, the test still uses "project.dump" rule. As I understand, you've 
written some new code for outputting projects/project-root. Can we rewrite 
'dump' in terms of your code?
