Hi Pedro,
I've just got the minimal "make" example to work with bjam and the Python 
port. That is, running bjam invokes the Python port, which loads the Jamroot, 
and then build actions are run.

Before committing this, there are a couple of questions to resolve. Before 
bjam loads Python modules it create an extension module "bjam". Any python 
module can do

import bjam
bjam.call('some-bjam-rule', 'a', 'b')

but "import bjam" means the module is only usable with bjam. Which gives two 
questions:

1. I've added Jamfile loading to the ProjectRegistry code. Do you find it 
desirable to split the logic into a separate module, so that project.py can 
be used without bjam? This should be easy -- just moving one class from 
project.py to another module, but maybe I worry too much?

2. Another issue is the BjamBuildSystem. Currently it generates the string 
that is to be executed by bjam. I think now it's time to make it do real 
calls to bjam. Is that OK with you? In my current version, calls to bjam are 
done via some kluge.
