You can use your .sbclrc to ensure that your local copy shadows the main
copy.

One thing to do would be to

1. (REQUIRE :ASDF)
2. Push the location of the local copy onto ASDF:*CENTRAL-REGISTRY*
3. (ASDF:LOAD-SYSTEM "ASDF")

As far as integration with Quicklisp is concerned, I have no idea, since
I don't use QL.  You should ask about that on a QL discussion place.

And what it says: if you have a cl-asdf package installed from something
like debian, get rid of it.

Fare disagrees with me, but I think this package is just a nuisance,
since every implementation I know of ships with ASDF bundled.
