  Far. It's almost OK. I did it with only 5% of space margin and
  without using METAL6. And, if you run in graphic mode, its 
  fascinating how the placer seems to find back the blocks...
  I add a picture in attachement.

  I just wanted to hint at this potential problem so people don't
  loose too much time next they encounter it. I slightly modified
  the top Makefile so I can install in a non-system directory,
  that is, the Coriolis install tree. This way I keep a system like
  directory tree but requiring only user permission.
    As a system administrator, I'm very very reluctant to directly
  install things in the system tree as root. Because after some
  time you loose track of what has been installed or not.
  So only packaged things (rpm, deb) sould go there as the packager
  keeps track for you.
