[Fluxus] install problem on linux mint15

[Christophe]

Hi, ... so i've installed racket 5.3.1, and the fluxus with scons
ADDONS=0, and everything seems to build correct... but... when i try 
to
launch fluxus, now i've got :

========================================================
default-load-handler: cannot open input file
  path: /usr/local/lib/fluxus-018/fluxus-video.rkt
  system error: No such file or directory; errno=2
  context...:
   standard-module-name-resolver
   standard-module-name-resolver
   standard-module-name-resolver
=========================================================

As i run scons with the ADDONS=0, I don't understand why ?
Anyway... thanks for help
