I'm afraid I cannot reproduce this, even on Windows. I replaced libmpi 
definition with "alias libmpi" (since I don't have any libs), and then 
defined 

alias fake_mpi ;

in Jamfile (I could not find any definition for that target). It does not 
generate the error. Could you modify generators.jam like this:

--- generators.jam 12 Nov 2004 08:11:04 -0000 1.75
+++ generators.jam 2 Dec 2004 14:54:46 -0000

And tell what's output then?
