nando its got nothing to do with cm or with use-system -- its ASDF  
thats having a problem. even if i zero out *central-registry* on  
ccrma it still looks under sbcl.

* (setq asdf::*central-registry* ())

* (progn
        (trace load)
        (pushnew "/user/h/hkt/cffi-070221/"  asdf::*central-registry*)
        (asdf::oos 'asdf:load-op 'cffi)
        )

this sounds to me like a probelm with sbcl's support of asdf. asdf is  
working in CLISP on CRRMA:

use-system is built ON TOP of asdf. use-system is a convenience  
function for people working in cm that have installed their lisp  
systems under a common ("system") directory. if asdf works  
then :directory works and if asdf doesn't respect directories then  
neither will use-system.   here on my machine  in SBCL i am loading  
cffi from its ususal place, then I load rts under a differnent  
directory than its usual place:


galen:/Lisp hkt$ cm -l sbcl

* (trace load)

(LOAD)

* (use-system :cffi)

; loading system definition from /Lisp/cffi-061220/cffi.asd into

* (use-system :rts :directory "/Users/hkt/rts/")
