Hi Juergen,

Thanks a lot for your input!
  
It is difficult to recreate the actual case, as it only happens with
the big source tree we have here ('good case! you might say).
    

This sounds familiar. I had the same problems until Jurko fixed a 
seemingly unrelated issuse with
 http://svn.boost.org/trac/boost/changeset/44195

See http://lists.boost.org/boost-build/2008/04/18737.php for the 
discussion.
  
Ok thanks!!
Please try the current bjam from trunk.

I have reactivated <install-dependencies> and everything works...
  
I will try it out and let you know - I would be very happy if it worked :)
Yours,
Dirk
