After adapting 'convert.jam' it worked on my small testcase but it 
did'nt work on my big project. So I slimmed down the project to soth. 
almost similar to the small test-case and I can't find why it does not 
work on the 'real-life' project. I've attached the project and in the 
main directory is the output of 'bjam -d2' (in the file bjam_log.txt).
As you can see, the exe is not linked to the fake-mpi library ;-(
