Hmm, the way ASDF is set up on Debian each user has her own spool area
for compiled fasls. So the source is installed in a central palce
(/usr/share/common-lisp/sources/...) but the compiled fasls go into
userspecific cache directories:


Once there used to be a fasl-cache for the whole system (and the 
common lisp controller was required to keep that cache up to date but
it turned out that that approach was more of a security headache then
a performance improvement). 

A "hypothetical" cm.deb would put all source files (including the 
ASDF package description) into /usr/share/common-lisp/sources/cm/
and then create a link from the asdf file into //usr/share/common-lisp/systems.
After that a simple (asdf:oos 'asdf:load-op :cm) would load Common Music
(allways with the most up-to-date fasls - even after an update of the
Lisp implementation).

Distributing binary lisp files is a nightmare - at least for the 
Open Source Lisps i know ....
